You can put this solution on YOUR website!
Use the quadratic equation,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-5%29+%2B-+sqrt%28+%28-5%29%5E2-4%2A2%2A4+%29%29%2F%282%2A2%29+
x+=+%285+%2B-+sqrt%28+25-32+%29%29%2F%284%29+
x+=+%285+%2B-+sqrt%28+-7%29%29%2F%284%29+
x+=+%285+%2B-+sqrt%287%29i%29%2F%284%29+
Do the second one exactly the same way.
