passing through (-5,2) and parallel to a line with slope -1/5

Differentiate the function : y = (6 + 4x)2

6=267a - 47b. We have figured out that b = (12 + 47a)/147. So we substitute: 6=267a - 47((12 + 47a)/147). We figure we can multiply both inside numbers by 47 and divide them by 147. Becomes 6=267a...

How do you do this. I just want to know. Thanks.

I already know the answer to this problem but I am having a hard time understanding how x equals 3 on the first column. Thus being able to figure out the rest.

A. f(x)=2(x+2)(x-1) B.f(x)=(x-1)2 -2 C.f(x)= (x-1)(x+3) D. f(x)=-(x+3)2 E. f(x)=-2x2-8x+3 F. f(x)=1/2x2-2
