Question 175187: desperately need some type of help.
USE FOIL

8) (7-2y)(10-3y)

9) (5z-2)(5z+2)

10) (x-6)²

11) (2-3x6)²

I will do 10 only.
10) (x-6)²
(x-6)² can be written as two factors:
(x - 6) (x - 6)
x times x = x^2
x times -6 = -6x
-6 times x = -6x
-6 times -6 = 36
We now have:
x^2 - 6x - 6x + 36
Combine like terms to get the final answer:
x^2 - 12x + 36
