Hey dude here is your Answer------------------------ ✔️❣️✔️ ❣️✔️ ❣️✔️ ❣️✔️ ❣️✔️ ❣️

$n(n - 1) \: (n - 2) \: = 60 \\ \\ = > \: 2n \: - n \: (n - 2) = 60\\ \\ = > {2n}^{2} \: - 4n \: - {n}^{2} + 2n \: = 60 \\ \\ = > {n}^{2} - 2n = 60 \\ \\ = > {n}^{2} - n = \frac{60}{2} \\ \\ = > </u></em></strong><strong><em><u>n²-n</u></em></strong><strong><em><u> \: = 30.......$

= > n² - n - 30 = 0

=> n²-6n+5n-30=0

=> n(n-6)+5(n-6)=0

=> (n+5) (n-6)....
