    Calculus 2 Integration

    I've got a homework question I reallly need answered quick, I have the question:
    Evaluate the Integral of (4x^2-9)^1/2

    I think a trig substitution could be in order here...but not sure.

    Thanks in advance for the help!

    Actually the substitution x = \frac{3}{2}sec(x) would be more useful.
