Weegy: 4
User: Divide x4 + 7 by x - 3.
x³ - 3x² - 9x - 27 R 88
x³ + 3x² + 9x - 27 R -74
x³ + 3x² + 9x + 27 R 88
User: Factor 9b2 - 4.
(3b + 1)(3b - 4)
(3b + 2)(3b - 2)
(3b - 2)(3b - 2)
Weegy: (a-b)(r+s). please rate this answer,
User: Factor 3x2 - 15x - 42.
3(x - 2)(x - 7)
3(x - 2)(x + 7)
3(x - 7)(x + 2)
Weegy: B.3(x - 2)(x + 7). 3 times (x-2) = (3x-6) multiplied by (x + 7) = 3x^2 - 15x-42.
User: Factor 3x2 - 15x - 42.
User: Select the correct difference.
