expand 3(n(n+1))

Solution

expand

3 (n (n + 1))

Solution

3 n^{2} + 3 n

Solution steps

3 (n (n + 1))

Remove parentheses:

(a) = a

= 3 n (n + 1)

Apply the distributive law:

a (b + c) = ab + a c

a = 3 n, b = n, c = 1

= 3 nn + 3 n \cdot 1

= 3 nn + 3 \cdot 1 \cdot n

Simplify

3 nn + 3 \cdot 1 \cdot n : 3 n^{2} + 3 n

= 3 n^{2} + 3 n
