For any multiple choice questions, the solution is the expression that is factored completely, even though several answers may be mathematically equivalent. Factor out the greatest common factor (monomial) ( ) 6x + 10 ( ) 25x - 30y ( ) 8x + 4y + 12 ( ) 22x - 12 ( ) 6x2 + 9x ( ) 24x2 - 28x ( ) 8y2 + 3y 21x3 - 14x2 + 63x 7(3x3 - 2x2 + 9x) x(21x2 - 14x + 63) 7x(3x - 2x + 63) 7x(3x2 - 2x + 9) 7x(3x3 - 2x2 + 9x) Cannot be factored (prime) 10x3 + 2x2 + 4x 10(x3 + 2x2 + 4x) 10x(x2 + 2x + 4) x(10x2 + 2x + 4) 2(5x3 + x2 + 2x) 2x(5x2 + x + 2) Cannot be factored (prime) 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) |
