+x%5E2+-+2x+=+15x+-+10+
+x%5E2+-+17x+%2B+10+=+0
a=1 and b=-17 and c=10
x+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2817+%2B-+sqrt%28+%28-17%29%5E2+-+4%2A1%2A10+%29%29%2F%282%2A1%29+
x+=+%2817+%2B-+sqrt%28+289+-+40+%29%29%2F%282%29+
x+=+%2817+%2B-+sqrt%28+249+%29%29%2F%282%29+
