The normal vector is given by the cross product of the vectors.

First, we must write the determinant in order to take the cross product of the two vectors:

where i, j, and k are the unit vectors corresponding to the x, y, and z direction respectively.

Next, we take the cross product. One can do this by multiplying across from the top left to the lower right, and continuing downward, and then subtracting the terms multiplied from top right to the bottom left:

The normal vector to the plane is found by taking the cross product of  and . Using the formula for taking the cross product of two vectors, where  and , we get . Using the vectors from the problem statement, we then get . In vector notation, this becomes .

To solve the problem, we use the fact that two parallel planes have the same normal vector. The equation of on of the planes is given, and from that we know its normal vector is , which is the normal vector of the plane in question

To find the normal vector to the plane containing vectors  and , we find the determinant of the 3x3 matrix 

Plugging in the vectors and solving, we get

The difference between zero and the zero vector is an important one, because the result of a cross product is always a vector (the dot product of two vectors gives a scalar).
