Solve a nonlinear equation

Hi, Could you please help me to solve this equation in terms of "q" when p=0.5;

((log(q*(p - 1) + 1)*(q*(p - 1) + 1))/log(2) - (q*log(-q*(p - 1))*(p - 1))/log(2))*(p*q - 1) + ((log(p - q*(p - 1))*(p - q*(p - 1)))/log(2) + (log((p - 1)*(q - 1))*(p - 1)*(q - 1))/log(2))*(p*q - p + 1) - (log(q + p*(p - 1)*(q - 1))*(q + p*(p - 1)*(q - 1)))/log(2) - (q*(p*(p - 1) + 1))/log(2) + (q*(p^2 - p + 1))/log(2) - (p*q - 1)*((log(-q*(p - 1))*(p - 1))/log(2) - (log(q*(p - 1) + 1)*(p - 1))/log(2))*(q - 1) - p*((log(p - q*(p - 1))*(p - q*(p - 1)))/log(2) + (log((p - 1)*(q - 1))*(p - 1)*(q - 1))/log(2))*(q - 1) - p*q*((log(q*(p - 1) + 1)*(q*(p - 1) + 1))/log(2) - (q*log(-q*(p - 1))*(p - 1))/log(2)) - (log(1 - p*q*(p - 1) - q)*(q + p*q*(p - 1) - 1))/log(2) - (log(p^2*q - q*(p - 1))*(q*(p - 1) - p^2*q))/log(2) + q*((log((p - 1)*(q - 1))*(p - 1))/log(2) - (log(p - q*(p - 1))*(p - 1))/log(2))*(p*q - p + 1) - ((q - 1)*(p*(p - 1) + 1))/log(2) + ((q - 1)*(p^2 - p + 1))/log(2) + (log(p^2*q - q*(p - 1))*(q - 1)*(p^2 - p + 1))/log(2) + (q*log(-(q - 1)*(p^2 - p + 1))*(p^2 - p + 1))/log(2) - (q*log(q + p*(p - 1)*(q - 1))*(p*(p - 1) + 1))/log(2) + (log(-(q - 1)*(p^2 - p + 1))*(q - 1)*(p^2 - p + 1))/log(2) - (log(1 - p*q*(p - 1) - q)*(q - 1)*(p*(p - 1) + 1))/log(2) - p*q*((log((p - 1)*(q - 1))*(p - 1))/log(2) - (log(p - q*(p - 1))*(p - 1))/log(2))*(q - 1) + p*q*((log(-q*(p - 1))*(p - 1))/log(2) - (log(q*(p - 1) + 1)*(p - 1))/log(2))*(q - 1) =0
