Question

factor n^2+16n+64

Answer 1

_x_=64
_+_=16
(x+_)(x+_)

Answer 2

(n+8)(n+8)=0

Answer 3

Use the PSF method for this case

Answer 4

Product = 64
Sum=16
Factor = 8, 8

Answer 5

therefore = (n+8)(n+8)

Answer 6

n=-8

Answer 7

I never knew what I was doing to solve this was called the PSF method! I just learned something new. :)

Answer 8
