Question

What are the answers to the following quadratic equation:
x^2-4x-12

Answer 1

6 and -2

Explanation:

x^2-4x-12

set up equal to zero

x^2-4x-12=0

lets factor:

(x-6)(x+2)=0

x-6=0

x=6

or

x+2=0

x=-2

Answer 2

x=6 x=-2

Explanation:

x^2-4x-12 = 0

Factor

What two numbers multiply to -12 and add to -4

-6*2 = -12

-6+2 = -4

(x-6)(x+2) =0

Using the zero product property

(x-6) =0 x+2 = 0

x=6 x=-2
