The two perfect square trinomial perfect are x^2 − 4x + 4 and x^2 + 10x + 25.What are trinomials?A mathematical expression with three terms or three monomials is called a trinomial. Polynomials having only three terms are known as trinomials.A perfect square trinomial is an algebraic expression that takes the  formax^2 + bx + c,A perfect square trinomial is gotten by the multiplication of a binomial with itself, and a binomial takes the form (x+a).Therefore, the two perfect square trinomial perfect are x^2 − 4x + 4 andx^2 + 10x + 25.To learn more about the trinomials refer to the link;
