You can put this solution on YOUR website!
p=+500+-+10x%5E%281%2F2%29 when x = 2500
p=+500+-+10%282500%29%5E%281%2F2%29
if you know that the square root of 2500 is 50
p=+500+-+10%2850%29
p=+500+-+500
p=+0
if you do not see that the square root of 2500 is 50,
you can factor 2500.
p=+500+-+10%2825%2A100%29%5E%281%2F2%29
apply ^1/2 to 25 and 100
p=+500+-+10%28%2825%29%5E%281%2F2%29%2A%28100%29%5E%281%2F2%29%29
p=+500+-+10%285%2A10%29
p=+500+-+10%2850%29
p=+500+-+500
p=+0
