I have a large polynomial equation:

U={(5.23114*10^-33) - (2.46244*10^-41)*w^2 - (1.61563*10^-50)*n^2*w^2 + (1.9846*10^-50)*w^4 - (8.07851*10^-60)*n^2*w^4 + (7.03976*10^-70)*n^4*w^4 - (2.76382*10^-60)*w^6 - (2.11373*10^-69)*n^2*w^6 + (2.36439*10^-79)*n^4*w^6 + (1.42753*10^-70)*w^8 + (1.51262*10^-79)*n^2*w^8 + (2.55365*10^-89)*n^4*w^8 - (3.06049*10^-81)*w^10 + (6.67939*10^-90)*n^2*w^10 + (9.50359*10^-100)*n^4*w^10 + (2.2245*10^-92)*w^12 - (2.62666*10^-100)*n^2*w^12 + (1.08981*10^-110)*n^4*w^12 - (7.01133*10^-111)*n^2*w^14}

It has 2 variables (n and w). I need to set the equation equal to zero and find all roots (values of w) for a given n value over a range of n and plot these curves on a graph. For instance, if the range I want is from n = -10,000 to 10,000 in increments of 100, how can I display this graph?

Thanks!
