I have this system of equations that I'm trying to run, but I don't know what to do to display the imaginary numbers in the solution. This is what I have so far:
syms K
eqn = K == (981 - 250*(K + (3^(1/2)*5^(1/2)*(400*K^2 + 981)^(1/2))/50)^2)^(1/2)/20;
sol = vpasolve(eqn,K);
disp('K=')
disp(sol)
Any help is greatly appreciated.

sol = vpasolve(eqn,K);
sol1 = vpasolve(K==eqn,K);
disp(sol)
disp(sol1)
