It can be factored.

We need two numbers that multiply to -12 and add to -4, so are two terms would be -6 and 2.

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

x = 6
x = -2

Answer:

x1= -2

x2= 6

Step-by-step explanation:

x^2-4x-12=0

x^2+2x-6x-12=0

x(x+2)-6(x+2)

(x+2)*(x-6)

one solution

x+2=0

x=-2

other solution

x-6=0

x=6
