uhhhh, why is this in physics? 
u should put this in the math group. u'll get more help.
not sure what the RRT is
x^2(x+3)-5(x-1) = 0
so that it's (x^2-5)(x+3)(x-1) = 0
so that means that x = sqrt(5), -3, or 1.
Find a third-degree polynomial equation with integer coefficients that has the roots 8 and 3i.
(x-8)(x^2+3)
sorry i can't help you with the rest... :'(
