Sarah made an error in determining the polynomial equation of smallest degree whose roots are -3, - 2, 5 and 3.
Review Sarah's work, identify the error and correct all work from that point forward
that is affected by this error. Include at least one sentence explaining her error. Use
proper mathematical vocabulary, appropriately.
(x + 3)(x + 2)(2x - 1)(x - 3) = 0
(x2 - 9)(x2 + x - 2) = 0
x4-9x2 + x3 - 9x - 2x2 + 18 = 0
x4 + x3 - 11x2 - 9x + 18 = 0
