Answer 1

D. distribute the 3 to each term in the parentheses by multiplying.

Watch:

Beginning 3(2x - 6 - x - 1)^2 - 2 + 4x

Step 1: simplify within the parentheses: 3(x-7)^2 - 2 + 4x

Step 2: Expand the exponent: 3 (x^2 -14x +49) - 2 + 4x

Step 3: distribute 3 to each term in the parentheses by multiplying

3x^2 - 42x + 147 - 2 + 4x

Step 4: you can do it.
