Question

What is the factored form of y=x^3+x^2−12x

Answer 1

x(x - 4)(x + 3)

Explanation:

y = x³ + x² - 12x

x(x² + x - 12)

x(x - 4)(x + 3)

Answer 2

x( x-4)(x+3)

Explanation:

x^3+x^2−12x

First factor out an x

x(x^2+x^−12)

Now factor inside the parentheses

What two numbers multiply to -12 and add to 1

4*-3 = -12

4+-3 =1

x( x-4)(x+3)
