Factoring Completely
 Factor each expression completely.For any multiple choice questions, the solution is theexpression that is factored completely, even thoughseveral answers may be mathematically equivalent. 9y3 - y2 - y9(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 + 16x4(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 - 32x8x(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 + yy(2x2 + 3x + 1)y(2x2 + 3x)(2xy + y)(x + 1)(2x + 1)(x + 1)y(2x + 1)(x + 1)Cannot be factored (prime)
