Question

Solve x2 − 4x = 12.

x = −3, x = 4

x = 3, x = −4

x = 6, x = −2

x = −6, x = 2

Answer 1

I'm not to sure about this.

Answer 2

x^2 - 4x = 12
x^2 - 4x - 12 = 0
Factor it and then solve for x.

Answer 3

Can you help me factor it

Answer 4

What values when multiplied give you -12 and when added give you -4.

Answer 5

-2?

Answer 6

x*y = -12
x + y = -4
you could think of it as this..
or you could look it like this
6* -2 = -12
6 + (-2) = -4

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