Hi everyone,
I try to solve an equation. Coefficient of this equations depends another variable like 'a' and i want to find the roots depend on 'a'. For example, i have an equation like "x^4+5*a*x^2+6*a=0" and i want to find the roots like x1=0.122a etc. How can i do that?
Thanks
Cem

Ran in:
syms x a
eqn = x^4+5*a*x^2+6*a==0 ;
s = solve(eqn,x)
s =

Ran in:
syms x a
eqn = x^3+5*a*x^2-6*a*a*x+a^3==0 ;
s = solve(eqn,x,'MaxDegree',3)
s =
