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 :( Thanks!
