    integral, tan inverse substitution.

    i'm trying to resolve a problem that i was shown in class, but i took horrible notes and am having trouble figuring out what to do. i need to find the integral of:
    dx/(2x^2+3)^2

    i think i need to use a tan inverse substitution... but i don't really know how to do it. can anyone help me out?

    Make the substitution x = \frac{\sqrt{3}}{\sqrt{2}} \, \tan \theta.
