Thanks a lot have got it

if $x^2 = x+3$ then $x^3 = ??$ Not sure about this would appreciate some help

My daughter was given this problem in an exam. She could not do it and was never given the solution. I can do the problem using trig but she has not been taught trig yet. She says that it can be done without trig using a more simple method that she doesn't know. Could somebody please explain...
