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

That's because the given answer is wrong. $\displaystyle 44y^2 - 22y - 22 = 22 (2y^2 - y - 1) = 22(2y + 1)(y - 1) = 44 \left(y + \frac{1}{2}\right)(y - 1)$.
Thankyou for the help. kateB
