Its been awhile seen I ask a question, but I need help with this inequality question.

Consider the inequality: x^2 > -2x+15

The solution of this inequality consists of one or more of the following intervals: (- Infinity,A), (A.B), and (B, Infinity) where A<B

Find A:_____

Find B:_____

How do I solve this question? It's been awhile seen I tired to solve inequalty question. Can someone give me a crash course to solve this?
