Question

Factor -4y2 + 12y - 16

Answer 1

4(y2 - 3y + 4)
-4y(y2 - 3y + 4)
-1(4y2 - 12y + 16)
-4(y2 + 3y - 4)

Answer 2

Factor \[y ^{2} + 3y - 4\]

What two numbers when multiplied together equal -4 and when added together equal +3.

Well, 4*-1=-4 and 4+(-1)=

The anwser is 4 and -1.

So:
\[(x+4)(x-1)\]

Answer 3

Totally factored:

-4(y+4)(y-1).
