Question

When factored completely, x3 − 13x2 − 30x is

Answer 1

Answer:

x (x - 15) ( x + 2)

Step-by-step explanation:

Start by factoring out x. Use a modified version of the distributive property.

x(x^2 - 13x - 30)

The second factor breaks down further into two facts in some form. The factors are 15 and 2

x(x   15)(x   2) One of them is positive and one negative. The larger number numerically (15) must be minus, because the 13 is minus.

x (x - 15) ( x + 2) is your complete answer.
