Have you studied the solution of Quadratic Equations at all?

Completing the Square?
Quadratic Formula?

Any of these will do. Let's see your work.

You do not say - what do you need to do?

You should state that you are required to "solve" for u.

Move all your terms to one side and have zero on the other:

15u^2 - 13u - 6 = 0

Now use the Quadratic Formula, with a = 15, b = -13, c = -6.

That's it. You will get two answers.
