Answer 1

Foil this out or (x+7)^2 . I am not sure what you are asking?

Answer 2

do you know how to do FOIL ?

Answer 3

\[(a+b)(a+b)=(a+b)^2=a^2+2ab+b^2\]

Answer 4

if u are every confused go back to the basics
(a+b)(a+b)=(a+b)*a + (a+b)(b) exapand an simplify

Answer 5

remember how a(a+b) = a*a+a*b
instead of a think of (a+b) as the new a now
(a+b)(a+b) = (a+b)*a + (a+b) * b
=a^2 +ab + ab + b^2
=a^2+2ab +b^2
