    Factor,
    n(n-1)=0
    Whenver the product of two number is zero one of them must be zero (if you want to be cool then say the reals have no zero divisors).
    Thus,
    n=0
    n-1=0
    Are the only possible solutions,
    Thus,
    n=0,1
    But you need to check, and indeed they are solutions.
