Answer 12

4x2 – 4x – 48

Factor out 4:
4(x^2 - x - 12)

Find two numbers that multiply to get -12 and add to get -1.

In this case -4, 3 works:

Split the middle term, -x, of the trinomial into two terms using those two numbers:
4(x^2 - 4x + 3x - 12)

Factor by grouping:
4(x(x-4)+3(x-4))

Factor out x-4:

4((x-4)(x+3))

Write the final form:
4(x-4)(x+3)
