Step-by-step explanation:
A perfect square trinomial is a three-term polynomial (also called a trinomial) that results from squareing a binomial. Every trinomial of the form: [tex]a^{2} +2ab+b^{2}[/tex], It is a perfect square trinomial.
In this case, it is necessary to divide the intermediate value of 8 by 2, and then square it, obtaining the result.
