Homework Statement
solve for x:
[ x / sqrt(x^2 + h^2) ] = [ d / sqrt(d^2 + h^2) ]
I need to solve for x.
Homework Equations
sq rt * sq rt = what is inside the square root
square both sides of an equation
The Attempt at a Solution
Can anyone help me remember how to get rid of the sqrt of x on the bottom of the left hand side? If I multiply by the sq rt of the ( ) I will have to do it on the other side, so I will still have the sq rt.
If I square both sides of the equation, I think that I would get: x^2 / (x^2 + h^2) = d^2 / (d^2 + h^2) Is that right? If so, I don't know where to go from there to solve for x?
