6x^2 - 11x - 10 = 0
(2x - 5)(3x + 2) = 0
2x - 5 = 0 or 3x + 2 = 0
x = 5/2 or x = -2/3

Which of the following polynomials has zeros at x = –4 and x = 7? 4x 2 - 7x - 11 4x 2 - 49 7x 2 - 4x + 28 x 2 - 3x - 28
Question

1 Answer/Comment
x^2 - 3x - 28 has zeros at x = –4 and x = 7.
x^2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0 or x + 4 = 0
x = 7 or x = -4
