What will be the maple code to find the values of the exponents of the given function?

Question

I have a mathematical expression of the form

$$f(m)=A-B*\left(\frac{m+1}{\psi}+\frac{K1*(1-\beta^{m+1})+K2*\alpha^{m-1}}{K3*\alpha^{m-1}}\right),$$ where $A,B,\psi,K1,K2,K3,\alpha,\beta$ are constants. Fixing the parameters, I want to find the values of $m$ with the variation of a particular constant, for which the $f(m)=0$ or $\approx 0$. What will be the maple code for this problem?
