Algebra II- (Factoring Perfect Square Trinomials)——— How do you solve this: x^2+8x+16

Answer 1

Even a perfect square trinomial you can factor as you normally would

x²+8x+16

(x )(x )

What are factors of 16 that would add to 8? 4 and 4

(x+4)(x+4) or (x+4)²

You can check by FOIL to confirm this is correct.
