How do you solve #10u^3-5u^2=0#?
This is a third degree equation without and independent term, therefore it can be solve though factorization. Start by factoring u:
Notice that, for this new equation to result in 0, any of the factors must me 0. If the first
Again, we have a case in which the first
Do notice that this method only works when the equation is equals zero and there is no independent term. We could also have taken a shortcut and factored
