Question

Factor this trinomial 2n squared plus 3n minus 9

Answer 1

(2n - 3) (n + 3)

Explanation:

2n squared + 3n - 9

This is (how we call it in spanish) "Aspa simple"

In this you bassically do the following

2n squared + 3n - 9

2n - 3 = 3n

1n + 3 = 6n

= (2n - 3) (n + 3)

First of all, 9 can be turned in 3 x 3, then 2n squared is also equal to 2n x n. Then with that we multiply 2n x + 3 = 6n . Then n x - 3 = -3n. And that's all.
