Question

Identify the factors of x2 − 4x − 12.

Answer 1

Answer:

(x+2)(x-6), factors are -6 and 2

Step-by-step explanation:

x^2 − 4x − 12

we find out factors whose product is -12  and sum is -4

-6 times 2 = -12

-6+2=-4

So two factors are -6  and 2

Now we use the factors -6 and 2 to factor x^2 -4x-12

x^2 -6x+2x-12

(x^2 -6x)+(2x-12)

take out GCF, x(x-6) + 2(x-6)

(x+2)(x-6)

Answer 2

(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.
