A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you solve when you have a negative exponent?

A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.

How do you solve negative integral exponents?

A negative exponent is simply the reciprocal of the positive exponent. So simply remove the negative sign and find the reciprocal. Thus, for example, 5-3 = 1/53 = 1/125

How do you write a decimal using a negative exponent?

When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)

Why does a positive times a negative produces a negative?

Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to be positive. (no matter if there is a positive sign in a math problem).

If you add a negative and a negative it equals?

Adding a negative number to a negative number makes a larger negative. In order to solve this you add the numbers together as a positive then add a negative sign.

How do you solve 5 minus negative 6?

To solve the problem 5 - -6, think of it as 5 + 6. You can do this because two negative numbers equal as positive number, and similarly two negative signs equal a positive. Therefore 5 --6 is 11.

How do you determine negatives or positives in math equations?

Numbers are justified as positive, which is usually written as just a number but can be written with a plus (+) sign in front of the number. (e.g. 15 or +15), or negative. Negative numbers are numbers in the negative integers, or below 0. They are written with a minus (-) sign in front of them. (e.g. -15) ---------------------------------------------------------------------------------- ..::To solve remember these rules::.. When multiplying: positive x negative = negative positive x positive = positive negative x negative = positive When dividing: positive / negative = negative positive / positive = positive negative / negative = positive When adding: In a positive + negative situation, if the negative number has a higher number than the positive (e.g. -25 + 10) then the number is negative, this is always true when adding a higher negative to a positive. If the positive has a higher number (e.g. 25 + -10) then it's just the opposite, it will be a positive number. -------------You can solve these very easily: 25 + -10 --> (25) + (-10) to keep it well organized and easier to work with,now just remember "Keep Change Change"... - keep 25 as it is, change "+" to a "-" and change the "-10" to a positive 10. As a result, you will have: 25 - 10. Now solve. Answer = 15 (positive). If for instance you have a negative + positive, the same rules apply (Keep Change Change) negative + negative = negative positive + positive = positive When subtracting: negative - positive (vice versa), use Keep Change Change as you did with adding positives and negatives. negative - negative, use Keep Change Change positive - positive, use Keep Change Change if the number you are subtracting is a higher number. (e.g. 10-15) If you need anymore help, try asking a more specific question again on Wikianswers, search for math websites on the web, or ask your teacher or college professor for help.

How do you solve a number to a negative power?

A number to a negative power is equal to One divided by number to its positive power. So, x^-2 is equal to 1/x2.

How do you solve negative powers?

The easiest way to solve negative powers is by writing it all out.You already know that positive powers (regular exponents) turn from something like 33 to 3 X 3 X 3 to equal 9 X 3, or 27.Essentially, negative powers works in a very similar manner.2-5 works out to this in expanded form: -2 X -2 X -2 X -2 X -2.It is best to start by multiplying that expanded form in pairs. So, you group -2 X -2, and then -2 X -2, and leave the last -2 for later. -2 X -2 is a positive 4 for both results. Now, multiply both of the 4s to get 16. Now multiply that by the remaining -2 to get -32.Tip: A shortcut method for doing this is recognizing that if the negative exponent is odd, then the answer will be multiplied just like a regular positive exponent, but the answer will be negative, and that if the negative exponent is an even number, the answer will be just like a regular positive exponent and the result will be a positive number.Ex: 2-3 = -8 , while 3-2 = 9.

How do you solve absolute-value equations and inequalites?

Absolute Value means the distance from 0, and so you should solve the equation with the number inside the Absolute Value lines as a positive and then solve again as a negative.

Why is there no solution to the square root of -169?

The answer is an imaginary number, because of the negative under the square root. The same number multiplied together will always be a positive number. For example, if you square negative one, the answer is positive one, because a negative times a negative is a positive. Because a square root undoes a square, there is no solution to the square root of a negative number. That's why your calculator could not compute this problem. However, there is a way to solve these types of problems by using imaginary numbers. The answer is 13i, where i is the square root of negative one.

A biased exponent is an exponent that is, in layman's terms, set aside when being used in high valued numbers, and basically just stored until the value of the number in the biased exponent needs to be used to solve an equation.

How do you solve the problem -2 plus 5 equals?

To solve -2 plus 5 equals, it's probably easier to start with the positive number and add the negative number to it. The equation will look like this: 5 + (-2) = Because you are adding a negative number, you actually have to subtract the 2, rather than add it, so your answer will be 3.

How do you solve adding negative and positive problems?

just think of the negative number as below the zero on the number line. just like the positive numbers are above the zero on the number line. then count out how far you have to go to get to your number. you can also treat the negative number like you a minusing that number take -3 and 7 -3 + 7 = 4 7 - 3 = 4

How do you solve integers and absolute value?

To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.

What is thirteen to the negative two power?

To get something to a negative power, first you must put it on the opposite side of the fraction it would be on currently. Also, when you do this, you switch the negative exponent to a positive exponent. 13^-2 1 = 1 13^2 Solve. 1 169 = 13^-2
