# Rewriting a constraint as a standard SOC constraint.

### FOIWATER

I am trying to rewrite this constraint as a second order cone constraint of the form $$||Ax+b|| \leq C^Tx+d$$

$$x^2-(x-5)y-yz+3(z-5)^2 \leq 1+x$$

I am having a hard time of knowing where to start.. any information appreciated.

I usually graph it, look at the surface from several angles, think about the projection in the coordinate planes, and scratch my head.
