I have the equation g^2+6*g*h+3h=0 for which I need to solve g in terms of h. Here is my attempt:
syms g h
g = solve('g^2+6*g*h+3*h=0')
For some reason this consistently only solves h in terms of g. Can someone point out to me what I am doing wrong?

solve() has an algorithm for selecting which variable to solve for when it is not told which one to solve for. The algorithm is based upon the letter the variable name starts with.
You should specify which variable you want solved for:
g = solve('g^2+6*g*h+3*h=0', 'g')

you need to use two equal signs
g^2+6*g*h+3*h==0
