Linearising compound pendulum equation


1. The problem statement, all variables and given/known data
Linearise T=2pi√(K^2 + h^2)/gh K is known constant

This is a compound pendulum equation, I want to plot some kind of formula with variable T against some kind of formula with variable H in order to find g from the gradient.

2. Relevant equations



3. The attempt at a solution

so i've got T/2pi all squared times g all substituted to x, h subbed to y and k^2 subbed to constant C and I've got the equation y^2 -yx + C=0 and tried to solve for y=x+β

I've tried implicit differentiation and it's gotten me nowhere
