expand n(n-1)(n-2)

Solution

expand

n (n - 1) (n - 2)

Solution

n^{3} - 3 n^{2} + 2 n

Solution steps

n (n - 1) (n - 2)

Expand

n (n - 1) (n - 2) : n (n^{2} - 3 n + 2)

= n (n^{2} - 3 n + 2)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

n (n^{2} - 3 n + 2) = n n^{2} + n (- 3 n) + n \cdot 2

= n n^{2} + n (- 3 n) + n \cdot 2

Simplify

n n^{2} + n (- 3 n) + n \cdot 2 : n^{3} - 3 n^{2} + 2 n

= n^{3} - 3 n^{2} + 2 n
