(n-1)!(n^2+n)

OpenStudy (anonymous):

does it help to know \(n^2+n=n(n+1)\)?

OpenStudy (anonymous):

Yes.. A little would it be n! ?

OpenStudy (anonymous):

no but close

OpenStudy (anonymous):

you also have \(n+1\) there

OpenStudy (anonymous):

Could I move the factorial to wherever or does it have to stay where it is?

OpenStudy (anonymous):

no it does not move you get \((n+1)!\) for this one

OpenStudy (anonymous):

Okay thank you VERY much. Sorry for all the questions, just joined Data Management 2 weeks late. Have a lot of catching up to do.
