Simplifying Factorials

  1. Jun 11, 2012 #1
    1. The problem statement, all variables and given/known data
    (n+1)(n+1)!+(n+1)! =(n+2)! simplify

    3. The attempt at a solution
    I need to know how to simplify this to show it is true. I know that the above statement is true, but I do not understand how to simplify the left hand side to show it.

    Thanks, I really have no idea where to begin and, frankly, it's kind of embarrassing as this is for a discrete math class :(

    Factorize LHS then you will get [(n+1)!][(n+1)+1] :smile:

    What is (n+1)x + x ?
