Factor 5x2-5x - 60.
5(x + 3)(x-4)
5(x - 3)(x + 4)
5(x-4)(x + 3)

Which shows one way to determine the factors of  x3  +  5x2  –  6x  –  30 by grouping? x(x2  –  5)  +  6(x2  –  5)x(x2  +  5)  –  6(x2  +  5)x2(x  –  5)  +  6(x  –  5)x2(x  +  5)  –  6(x  +  5)

Solve the equation - 2(m -30) = -6m a-15 b-13 c-8 d8

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 20 = x a. 5, 4 b. -5, -4 c. -5, 4 d. 5, -4
