Hi colleages. can you help me to solve the cubic equation below:(adsbygoogle = window.adsbygoogle || []).push({});

2N(Ep-En)hp^3(x)-3[M(x,t)(Ep-En)-2NEnh]hp^2(x)-6Enh[M(x,t)+Nh]hp(x)+Enh^2[3M(x,t)+2Nh]=0 notice that all variables in the equation are dependent on x only, except M is dependent on x and t.

En, Ep, N and h are constants.

i know the solution when the equation dependent on one variable, but the problem is that M dependent on two variables x and t.

please help me and i will be very grateful for you...
