You can put this solution on YOUR website!
A=2x%5E2%2B4xh
2x%5E2%2B4xh-A=0
use quadratic formula
if ax^2+bx+c=0 then
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
so our a=2 our b=4h and our c=-A
x+=+%28-4h+%2B-+sqrt%28+%284h%29%5E2-4%2A2%2A%28-A%29+%29%29%2F%282%2A2%29+
x+=+%28-4h+%2B-+sqrt%28+4%284h%5E2%2B2A%29+%29%29%2F%284%29+
x+=+%28-4h+%2B-+2sqrt%28+%284h%5E2%2B2A+%29%29%29%2F%284%29+
x+=+%28-2h+%2B-+sqrt%28+%284h%5E2%2B2A+%29%29%29%2F%282%29+
