You need to provide more detail. What is Dm? What is F(M) and howdoes it connect with the first equation? Are you trying to find M? ...

Do you mean you want to find the value(s) of M that make the function F(M) = 0.8M(1+M^2)-10 equal to zero? If so then use Matlab's roots function
% F = 0.8*M^3 + 0.8*M - Dm;
% F = 0.8*M^3 + 0*M^2 + 0.8*M -Dm
Dm = 10;
coeffs = [0.8 0 0.8 -10];
M = roots(coeffs);
disp(M)
