How do you complete the square of \(\displaystyle (-2y^2 +2yz -z^2)/2\)

into the form \(\displaystyle -(a((x-b)^2))/2\)

Thanks Adam

\(\displaystyle \frac{-2y^2 + 2yz - z^2}{2}\)

\(\displaystyle -\frac{y^2 + y^2 - 2yz + z^2}{2}\)

\(\displaystyle -\frac{y^2 + (y-z)^2}{2}\)

... that's about all i could do with it.

It cannot be put into that form. (By the way, what is x meant to be? The variables of your problem are y and z).
