I am working on a problem which requires the quadratic formula to solve. The problem is as follows:

For which value(s) of p does the equation px^2 - 10x + p = 0 have exactly two solutions?

I have plugged in the numbers and come up with:

x = 10 +/- (√-10^2 - 4p^2)/2p

From there I am unsure of what I need to do to get p by itself for the solution.

Any help would be appreciated.

Thanks,

Matty
