You can put this solution on YOUR website!
Which do you mean:
4p%5E2-4=0
OR
%284p%29%5E2-4=0
?

Either way, there is the difference of two squares.
4p%5E2-4=%282p%2B2%29%282p-2%29.
%284p%29%5E2-4=%284p%2B2%29%284p-2%29.
Pick the one that you need or have.

Other than that, if a and b are real numbers, the ab=0 means that either a=0, or b=0 or a=b=0.
