Factor completely 2x2 − 6x − 36.

2(x − 3)(x + 6)
2(x − 6)(x + 3)
(2x − 4)(x +9)
(2x − 9)(x + 4)

To factor out completely, we should have reached the most simplified form,
first we should take out 2.
2(x2 - 3x - 18)
then we should factor out the inside of the parenthesis,
2(x - 6)(x + 3)
And that's the most simplified and factored out form.

The final answer is then the second option, 2(x − 6)(x + 3)
