expand 2n(n^2+3n+4)

Solution

expand

2 n (n^{2} + 3 n + 4)

Solution

2 n^{3} + 6 n^{2} + 8 n

Solution steps

2 n (n^{2} + 3 n + 4)

Apply the distributive law:

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

2 n (n^{2} + 3 n + 4) = 2 n n^{2} + 2 n \cdot 3 n + 2 n \cdot 4

= 2 n n^{2} + 2 n \cdot 3 n + 2 n \cdot 4

Simplify

2 n n^{2} + 2 n \cdot 3 n + 2 n \cdot 4 : 2 n^{3} + 6 n^{2} + 8 n

= 2 n^{3} + 6 n^{2} + 8 n
