-5x%5E2=-5x%2B9
0=5x%5E2-5x%2B9
or
5x%5E2-5x%2B9=0->solve by using the quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ since in your case a=5, b=-5, and c=9 we will have
x+=+%28-%28-5%29+%2B-+sqrt%28+%28-5%29%5E2-4%2A5%2A9+%29%29%2F%282%2A5%29+
x+=+%285+%2B-+sqrt%28+25-180+%29%29%2F10+

x+=+%285+%2B-+sqrt%28+-155+%29%29%2F10+
x+=+%285+%2B-+sqrt%28155+%29%2Ai%29%2F10+
solutions: we have complex solution

x+=+%285+%2B+sqrt%28155+%29%2Ai%29%2F10+
or
x+=+%285+-+sqrt%28155+%29%2Ai%29%2F10+
