I'm trying to learn linear algebra using Schaum's outline and this is one of the practice problems:(adsbygoogle = window.adsbygoogle || []).push({});

Find and equation of the hyperplaneHinR^{4}that passes throughP(3,-4,1,-2) and is normal tou=[2,5,-6,-3]

The equation is in the form 2_{x1}+5_{x2}-6_{x3}-3_{x4}=k

They say to substitutePinto the equation to obtaink=-26 but I keep coming up withk=-14. This is simple math but I'm clearly missing something. Where am I going wrong?
