1. ## Factors

Hello, I need help in factorizing this expression please:
44y^2-22y-22

^2 is my symbol for squared.
I do not understand how the answer is:

1/44(y-1)(y+1/2)

Thankyou,
KateB

Neither do I. That's because the given answer is wrong.

$44y^2 - 22y - 22 = 22 (2y^2 - y - 1) = 22(2y + 1)(y - 1) = 44 \left(y + \frac{1}{2}\right)(y - 1)$.

Thankyou for the help.
