I'm given three points A(1,-2,1), B(3,2,2) and C(-2,1,-5) and I'm asked to find plane equation for it. I know to start it out, you'd take dot product of one of components with others, then take the cross product of that to get your x

Dot products:

Cross product:

_{0, }y_{0}, and z_{0 }but after that I'm confused. Would someone mind helping me out to understand how the answer gets to 3x-y-2z-3=0? Thanks in advance.Dot products:

**AB**=(2,4,1) and**AC**=(-3,3,-6)Cross product:

**AB**x**AC**=(-27,9,18)
