    you have two variables? i am not sure if you can just solve the equation for a without knowing what x is. if you break it down a little you can get:

    -45a^3 + (x-4)a^2 = 0
    if you set x = 0, you get:
    -45a^3 = 0 in which case a=0
    if you set x = 5, you get:
    -45a^3 + a^2 = 0, which can be rewritten as:
    a^2(-45a + 1) = 0
    in which case a = 0, and 1/45)

    i dont know, i havent taken anything multivariable yet, so maybe there is a different way to look at it.
