| May 19, 2018 at 6:53 | comment | added | PossiblyDakota | @scaaahu I though that they were be taking to 0 exponent but then how would that help with being divisible by (x-y) I have no idea. I must need sleep. | |

| May 19, 2018 at 6:49 | comment | added | Nobody | Still wrong. Take out "$ = 1 -1 = 0$". How did you get the idea $x = y = 1$? They are variables. | |

I'm loosing my mind. Removed 8(0)

| May 19, 2018 at 6:45 | comment | added | PossiblyDakota | @scaaahu Why would they mark me off. But never mind I see the error now. | |

| May 19, 2018 at 6:37 | comment | added | PossiblyDakota | @scaaahu I'm not in school. I just do math because I want to understand Donald Knuth. But just out of curiosity why would they do that? Edit: Wait no. I see it. | |
| May 19, 2018 at 6:33 | comment | added | Nobody | In your base case, you need to take out "$= 1 - 1 = 0 = 8(0)$". Your TA will take out partial credits when he sees it. | |

| May 19, 2018 at 6:14 | comment | added | Frank Lu | Your last equality is false. $(x^n+y^n)(x-y)=x^{n+1}+xy^n-x^ny-y^{n+1}$ | |
