Question

How Do I square A Binomial like (x+8)^2?

Answer 1

You can write it multiplied by itself and foil, since that's all squaring something is:

(x+8)(x+8) =

gives you: x^2 + 16x + 64

Answer 2

its called FOIL: first outer inner last
write (x+8)(x+8)
first:(x)(x) outer (8)x inner 8x last (8)(8)
then add them up :
x^2+16x+64
