Nakon što je izmewao sve što je planirao, shvatio je da je vrijeme za jedan masni mogging. Međutim, kao pravi sigma, on ne voli ovisiti o drugima, ali mora priznati da su za mogging neophodni prijatelji. Pomozite mu otkriti koliko mu prijatelja treba da ih W rizz izmogga ko freddy fazbear tako da riješite sljedeću jednadžbu:

x^7-3x^6-3x^5+17x^4-9x^3-21x^2+27x-9=0.

Naravno, svi znaju da je broj prijatelja uvijek iracionalan i da nikad nije pozitivan. Broj prijatelja treba napisati u decimalnom zapisu, sa 3 decimalna mjesta uz standardna pravila zaokruživanja (5,6,7,8,9 ide naviše, a 0,1,2,3,4 naniže).

After he finished all his mewing, Baby Gronk realized it was time for some serious mogging.
