    There are many ways you can go. I'm going to start out factoring the whole thing.

    (x+9) (x-8) = 0

    seperate these into two different equations.

    x+9 = 0 and x-8 = 0

    x = - 9 x=8

    Make sure you check it by substituting. Sometimes you might have to reject an answer. In this case you don't. Therefore, 8 and - 9 are your roots!
