6%2Ax=%28x%5E2+%2B+6%29+%2B+%28x%5E2+%2B+12%29
6%2Ax=2x%5E2+%2B+18
2x%5E2-6x%2B18=0
x%5E2-3x%2B9=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-3%29+%2B-+sqrt%28+%28-3%29%5E2-4%2A1%2A9+%29%29%2F%282%2A1%29+
x+=+%283+%2B-+sqrt%28+9-36+%29%29%2F%282%29+
x+=+%283+%2B-+sqrt%28+-27+%29%29%2F%282%29+
x+=+%283%2B-+3%2Asqrt%283%29i+%29%2F%282%29+
