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

What is the multiplicative inverse for 5340?

Another name for multiplicative inverse is reciprocal. Basically, you write the number as a fraction and you reverse the numerator and the denominator. In this case, the multiplicative inverse is 1/5340.

Another name for additive inverse?

As far as positive numbers are concerned, the additive inverse of a positive number is a negative number with the same magnitude (i.e. the additive inverse of 5 is -5). It would be wrong to simply say that "negative" and "additive inverse" are correct, because the additive inverse of a negative number is a positive number.

What is the name of the number that when added to another equals 1?

There is a complement that when added equals one but you may be thinking of multiplying. A number times its reciprocal (multiplicative inverse) is equal to one. A number added to its additive inverse (opposite) is equal to zero.

What is a multiplicative inverse?

The multiplicative inverse for the number x is the number 1/x, such that their product is 1. The name for a multiplicative inverse is the reciprocal (opposite).The multiplicative inverse of a fraction is found by making the numerator the denominator and the denomination the numerator, such that the reciprocal of 3/4 would be 4/3. You are simply "flipping the fraction over."Dividing by a fraction is the same as multiplying by its inverse, or reciprocal.Example: 6 divided by 2/3 = 6 times 3/2 = 18/2 = 9so that are 9 two-thirds sections in 6 wholes.

How do you get the multiplicative inverse?

Multiplicative inverses are two numbers whose product is one.Another name for multiplicative inverse is reciprocal. The reciprocal of 2/3 is 3/2. 2/3 X 3/2 = 6/6 = 1. The multiplicative inverse of 7 is 1/7. 7 X 1/7 = 7/7 = 1.

What is the name for 2 given integers that combine to be zero?

Integers that add to zero (like 3 and -3 or 5 and -5) are called additive inverses. The general formula for an additive inverse is x + (-x) = 0, where x and (-x) are additive inverses.

Why 0 does not have a multiplicative inverse?

As n gets very small, 1/n goes towards infinity. A multiplicative inverse of 0 would be some number x, such that 0x=1. This is impossible with the real numbers we use, since 0x=0 for any number x. One might be tempted to invent a new number (calling it "infinity", "nullity", or any other name) that would be the inverse of 0. Of course, then you're not dealing with real numbers anymore, you're dealing with real numbers plus this invented number. There are serious issues even with this approach. Again, let x be this "multiplicative inverse of 0". Then 0*1=0 and 0*2=0. So 0*1 = 0*2. Multiply both sides by x to get x*0*1 = x*0*2. Since x*0 is 1, this means 1*1 = 1*2. So 1=2, which is an absurd conclusion. As you can see, there are good reasons not to allow a multiplicative inverse for 0 - it breaks all the laws of multiplication we're accustomed to.

Name the property illustrated by the following x plus -x equals 0?

This is the existence of additive inverse: For every number, x, there exists a number, denoted by (-x), such that x + (-x) = (-x) + x = 0.

Define property of reciprocals?

A reciprocal is the number you have to multiply a given number by to get 1. Ex) you have to multiply 2 by 1/2 to get 1. therefore the reciprocal of 2 is 1/2 As implied above, a property of two reciprocals is that their product equals 1. Another name for "reciprocal" is "multiplicative inverse."

Must the opposite of a rational number be a rational number?

No. A rational number is one that may be represented as a simple multiple, or a division. Such as one times seven, or three times seven; OR one divided by seven, or three divided by seven. Or similar.A rational number, if a fraction, when multiplied by the divisor of the fraction, will give a simple whole number. e.g. 7/5, when multiplied by 5 becomes the whole number 7.An irrational number is one that cannot be formed by a simple ratio, or a simple division. e and pi are a couple of common irrational numbers. [irrational demonstrates where the name comes from.]No number can be found which will convert them, by multiplication, into a whole number.
