If u = 3, what's the inner product #u*u#?

How do I find the pointnormal form of the equation of the plane containing the point (3,4,3) and perpendicular to (4,1,2)?

What are the scalar equations of the equation of the line through the point (4,6,3) and perpendicular to the plane 5 x+y+2 z=7?
Also I have to write the answer in the form [a+b*s, c+d*s, e+f*s] where s is a parameter.
