Find and equation of the hyperplane

*H*in

**R**

^{4}that passes through

*P*(3,-4,1,-2) and is normal to

*u*=[2,5,-6,-3]

The equation is in the form 2

_{x1}+5

_{x2}-6

_{x3}-3

_{x4}=

*k*

They say to substitute

*P*into the equation to obtain

*k*=-26 but I keep coming up with

*k*=-14. This is simple math but I'm clearly missing something. Where am I going wrong?
