    Solving an equation

    I was not real sure where to post it but here it goes. I am trying to solve the depth of sheet pile needed and the equation I am solving for is: g=gamma D^4-[8p/g(Kp-Ka]D^2-[12PL/g(Kp-Ka)]D-[2P/g(Kp-Ka)]^2=0 this reduces to D^4-54.54D^2-1227.1D-13.63^2=0 My problem is how to solve for D, I...
