Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
That is an equation already solved for h. What are you looking for? It appears to be a quadratic equation with the variable, t. You can solve for t. You would treat just t as the only variable, and put the equation into the typical, "=0" form, and use general solution for a quadratic equation:
Your solutions for t are these:
OR
You might then take, for example the "+" form, as the simpler looking:
and the "-" form, as:
