You can put this solution on YOUR website!
You can make some sensible trials and test each to find if a factorization will work. If that becomes a long process, you can use more advanced a method.

Use the equation in its equivalent form of 8x%5E2%2B10x-3=0.

The lesson referenced also gives the general solution of a quadratic equation.
x=%28-10%2B-+sqrt%2810%5E2-4%2A8%2A%28-3%29%29%29%2F%282%2A8%29
x=%28-10%2B-+sqrt%28100%2B96%29%29%2F%282%2A8%29
x=%2810%2B-+sqrt%28196%29%29%2F%282%2A8%29
x=%28-10%2B-+14%29%2F%282%2A8%29
x=%28-5%2B-+7%29%2F8
