normal vector to a plane

[mathstresser]

A normal vector to the plane that contains the points at the end of all three vectors drawn in standard position.

a= <4,-1,3>
b= <-2, -5, 4>
c= -3, 5, -2>

So, in this problem, do I find vector ab and vector ac. Then do the cross product?

Would that just give the nomal vector to the original vectors?

What would give me the normal vector to the plane?

The normal is \(\displaystyle \L
N = \left( {\vec{ab} } \right) \times \left( {\vec{ac} } \right)\).
