3x%5E2%2B17x%2B45=12
3x%5E2%2B17x%2B45-12=12-12
3x%5E2%2B17x%2B33=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
where a=3, b=17, c=33
x+=+%28-17+%2B-+sqrt%28+17%5E2-4%2A3%2A33+%29%29%2F%282%2A3%29+
x+=+%28-17+%2B-+sqrt%28+289-396+%29%29%2F%286%29+
x+=+%28-17+%2B-+sqrt%28+-107+%29%29%2F%286%29+
x+=+%28-17+%2B-+i%28sqrt%28+107+%29%29%29%2F%286%29+
