Intermediate Algebra
Incorrect — FOIL yields 16x2−18x+916x^2 - 18x + 9, so the student's middle term is off by −6x-6x
Incorrect — the correct factorization is (8x−3)(2x−3)(8x - 3)(2x - 3) because you must distribute coefficients evenly
Correct — the trinomial is a perfect square, and the factors expand to give 16x2−24x+916x^2 - 24x + 9 when FOIL is applied
Cannot be determined without computing the discriminant first to see if roots are rational
