Factor each expression completely. For any multiple choice questions, the solution is the expression that is factored completely, even though several answers may be mathematically equivalent. 9y3 - y2 - y 9(y3 - y2 - y) y(9y2 - y - 1) 1(9y3 - y2 - y) y(9y2 - y - y) y(9y2 - y) Cannot be factored (prime) 6x2 + 21x + 15 (3x + 3)(2x + 5) 3(2x2 + 7x + 5) (x + 1)(6x + 15) 3(x + 1)(2x + 5) (x + 1)(2x + 5) Cannot be factored (prime) 20x2 - 70x + 60 (x - 2)(2x - 3) 10(2x2 - 7x + 6) 10(x - 2)(2x - 3) (10x - 20)(2x - 3) (x - 2)(20x - 30) Cannot be factored (prime) 12x3 + 32x2 + 16x 4(3x2 + 2x)(x2 + 2) 4x(3x2 + 8x + 4) (3x + 2)(x + 2) x(3x + 2)(4x + 8) 4x(3x + 2)(x + 2) Cannot be factored (prime) 8x3 - 32x 8x(x - 2)(x + 2) 8x(x2 - 4) 8(x3 - 4x) 8(x2 - 2)(x + 2) x(8x - 16)(x + 2) Cannot be factored (prime) 2x2y + 3xy + y y(2x2 + 3x + 1) y(2x2 + 3x) (2xy + y)(x + 1) (2x + 1)(x + 1) y(2x + 1)(x + 1) Cannot be factored (prime) |
