Question

Factor completely
x2 –x–6?

Answer 1

you need factors of -6 that equal -1, i.e., -3*2=-6 and -3+3=-1, then\[x^2-x-6=(x-3)(x+2)\]

Answer 2

what?

Answer 3

The answer is (x+2)(x-3)
The reason for this is we need to ask ourselves, what two numbers add to make -1 and multiply together to make -6?
The solution -3 and +2.
-3 + 2 = -1
-3 * -2 = -6
So we have (x+2)(-3)
