#### Answer

Square of Binomial

#### Work Step by Step

It is in the Square of Binomial form which is
$a^{2}$ + 2ab + $b^{2}$ = $(a+b)^{2}$
This is because the first and last term are squared in the polynomial and the middle term is +2 times the first and last term. Thus it follows the rule of Square of Binomial.
