Question

Whats is x2 - x - 12 = 0

Answer 1

x = -3 or x = 4

Explanation:

`x^2-x-12=0`

`(x+3)(x-4)=0`

`x + 3 = 0`

`x = -3`

`x - 4 = 0`

`x = 4`

Answer 2

x=-3 or x=4

Explanation:

x2−x−12=0

Step 1: Factor left side of equation.

(x+3)(x−4)=0

Step 2: Set factors equal to 0.

x+3=0 or x−4=0

x=−3 or x=4
