Having a really hard time with factoring, not sure why...

please help?

Solve the Equation by Factoring:

-6x - 2 = (3x + 1)2

and

7 - 7x = (4x + 9)(x - 1)
Solution
-6x - 2 = (3x + 1)2
-2(3x+1) = (3x+1) 2
3x+1( 2+2) = 0
3x+1 = 0
x = -1/3

xand

7 - 7x = (4x + 9)(x - 1)
7(1-x) = (4x+9)(x-1)
4x+9 = -7
4x = -7-9 = -16
x = -16/4 = -4
.
