I don't know how to factor this, what should I do to get the right answer​
lina2011 [118]

Answer:

Step-by-step explanation:

First, you can reduce it

4(n^2-11n+30)

This should make it easier to work with. But remember, keep the 4 there. You cannot just get rid of it because it would change the value of the equation

Now find factors of 30 that have a difference or ad up to 11.

Factors of 30:

1, 30

2, 15

3, 10

5, 6

Ahh  yes, 5 and 6 add to 11

4(n-5)(n-6)
