Follow the method in Step 1 to determine if the third expression is a perfect square trinomial. The first term and the third term of the third trinomial, h² - 13h + 36, are perfect squares. h² = (h)² 36 = (6)² Because the h-term is negative, if the trinomial is a perfect square, then it is the square of a binomial difference. Find the square of the binomial formed by the difference of the square roots of the perfect squares, (h - 6)². You can use the distributive property to square the binomial. Or you can use the rule for squaring a binomial difference, (a - b)² = a² - 2ab + b², with a = h and b = 6. Compare the original trinomial to the square of the binomial. (h-6)² = (h-6)(h-) =h² - (2)(h) ( ) + (6)² = h² - h + 36
