Homework Help: Quadratic surfaces question

  1. Oct 14, 2011 #1
    1. The problem statement, all variables and given/known data

    Write the following quardatic surface equation as a sum of multiples of
    squares of independent linear functions


    2. Relevant equations

    3. The attempt at a solution

    Please see attachment.

    nb. there is no answer provided by the tute, but from all the previous exercises, it should
    be in the form of something like [itex](ax + by -cz)^{2} + (dx + ey -fz)^{2} + g^{2}[/itex]

    My problem is that I have no effective and quick way to solve these sorts of problems using the complete the squares method.

    I would have to spend hours trying to find a combination that will make the equation balance out
