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 are the rules when adding or subtracting negative numbers?

When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7


You start with -6 you add -10 then take away -2 what do you get?

You start with -6you add (+)-10then take away (-)-2what do you get?Adding a negative is subtracting, and subtracting (taking away) a negative is adding. (-6) + (-10) - (-2) = ?-6 - 10 + 2 = -14 ◄

What to do when you're subtracting or adding integers and the signs are different?

The sum or difference will take the sign of whichever number is larger (disregarding the signs). -6 + 8 = 2 6 + -8 = -2 8 - (-6) = 14 -8 - 6 = -14

What is the rule when subtracting fractions with uncommon denominators?

You first find a common denominator (eg for 2/3 and 4/7, it would be changed to 14/21 and 13/21) and then subtract them for each other. When doing this, you always multiply the numerator and denominator (top and bottom numbers) by the same amount

What is the connection between the LCM and adding or subtracting fractions?

Two fractions having different denominators cannot be added or subtracted directly. They need to be converted to equivalent fractions having the same denominator to enable the addition or subtraction to take place. It is possible to use the product of the denominators of the original fractions as the common denominator but it simplifies the mathematics if the lowest common multiple of the two denominators is used. EXAMPLE : Add 2/5 and 3/7. The lowest common denominator (also the LCM) of 5 and 7 is 35. 2/5 is equivalent to 2 x 7/5 x 7 = 14/35 : 3/7 is equivalent to 3 x 5/7 x 5 = 15/35 2/5 + 3/7 = 14/35 + 15/35 = 29/35


What is IXV in roman numerals?

IXY would be 14 in roman numerals because an "i" in front of something would be subtracting, and "X" means 10. Meaning you do 10 - 1 = 9 then adding 5 because of "V" meaning 5. 9 + 5 =14. IXY = 14


What is 3.5 gallons minus 14 quarts?

There are 4 quarts in a gallon. Therefore, 3.5 gallons is equal to 14 quarts. Subtracting this from 14 quarts gives 14 - 14 = 0 quarts.


What is the rule in adding fractions having the same denominator?

Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
