So keep in mind a negative minus a negative is the same as a negative plus a positive. For example -9-(-7) is the same as -9+7 because the 2 minuses cancel each other. So all you have to do is -9 + 7 = -2. If you’re confused, try looking on a number line and count it.

Answer:

18q^2 - 52q + 32

Step-by-step explanation:

2q(9q) + 2q(-8) + -4(9q) + -4(-8)

18q^2 - 16q - 36q + 32

18q^2 - 52q + 32

18q^2 - 52q + 32
