Question

Factor this trinomial: x2−2x−24

Answer 1

For this case we must factor the following expression:

$x ^ 2-2x-24$

We must find two numbers that when added together give "-2" and when multiplied by "-24"

These numbers are:

$-6\ and\ +4\\-6 + 4 = -2\\-6 * + 4 = -24$

So:

$x ^ 2-2x-24 = (x-6) (x + 4)$

Answer:

$(x-6) (x + 4)$

Option A and D

Answer 2

It’s (x-6)(x+4) so the first one and last one
