Question

how can I Prove that it is true through an algebraic proof, identifying each step?
(x+a)^2=x^2+2ax+a^2

Answer 1

(x+a)(x+a)=?

Answer 2

\[(x+a)^2=(x=a)(x+a)=x(x+a)+a(x+a)=x^2+ax+ax+a^2=x^2+2ax+a^2\]

Answer 3

so when its broken down into "solving" it would be
(x+a)^2=x^2+2ax+a^2
(x+a)(x+a)=x(x+a)+a(x+a)
x^2+ax+ax+?

Answer 4

the last term is a^2 ! :)

Answer 5

thanks:) so that's the answer? or would I have to do more?
