    Help on how to do equation.

    Hi,
    I need to know how to solve for S in the following:

    S2=2HS-Z

    I've tried what I can think of as a current Algebra 2 student, but I can't figure it out. Plugged in to a TI-89 it shows the answer as S=(H2-Z)1/2 -H (sorry, I don't know how to insert a square root into the equation.)

    Re: Help on how to do equation.

    Just transfer all terms on one side. S^2 - 2HS + Z =0. It is a quadratic in S. Use the formula for solving quadratic equation and you would get the result.
