Find a nonzero vector orthogonal to the plane through the points P, Q, and R, P(0,-2,0), Q(4,1,-2), R(5,3,1).

**Answer**: < -1, -7, 6 > or <1, 7, -6 >

## Explanation

You may have gotten < 1, 7, -6 > instead by using a different order for the cross product or picked two different vectors on the plane.
