You can put this solution on YOUR website!
The quadratic formula is
-b+%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29/%282%2Aa%29
Looking at your equation of p%5E2%2B2p-5+=+0
we can see that a = 1, b = 2 and c= -5. Don't forget the signs.
PLug these into the quadratic and you get
-2 +- sqrt(4 - 4*1*-5) / 2(1)
(-2 +- sqrt(24))/2
(-2 +- 2sqrt(6)) / 2
-1 +- sqrt(6)
