Answer 1

The first rule of factoring is to try to factor a common factor out of all terms.
Is there a common factor of 4, 12, and 16?

Answer 2

4

Answer 3

Yes, so you can take out a 4.

\(\large - 4y^2 + 12y - 16\)

\(\large = 4(-y^2 + 3y - 4)\)

Since we see that the choices have a factor of -4 pulled out, not 4, let's factor out a -1 out:

\(\large = -4(y^2 - 3y + 4)\)
