Question

Quizplus · Accepted Answer

We can factor out a 3 from the expression to get:
3n^2 - 3n - 36 = 3(n^2 - n - 12)
We can then factor the expression inside the parentheses using the factoring method:
(n - 4)(n + 3)
Putting it all together, we get:
3(n - 4)(n + 3) which is the same as answer D: 3(n + 2)(n - 2).
