In Exercises 89-92, use a graphing utility to graph the function on each side of the equation in the same viewing rectangle. Use end behavior to show a complete picture of the polynomial on the left side. Do the graphs coincide? If so, the factorization is correct. If not, factor correctly and then use your graphing utility to verify the factorization. 89. 4x2 – 12x + 9 = (4x – 3)2 90. 2x3 + 10x2 – 2r – 10 = 2(x + 5)(x² + 1) 91. x* - 16 = (x² + 4)(x + 2)(x – 2) 92. x + 1 = (x + 1)
