Solve n(n+2)(n-2)

$$n ( n + 2 ) ( n - 2 )$$

Evaluate

$$n\left(n^{2}-4\right)$$

Solution Steps

Use the distributive property to multiply n by n+2.

$$\left(n^{2}+2n\right)\left(n-2\right)$$

Apply the distributive property by multiplying each term of n^{2}+2n by each term of n-2.

$$n^{3}-2n^{2}+2n^{2}-4n$$

Combine -2n^{2} and 2n^{2} to get 0.

$$n^{3}-4n$$

Expand

$$n^{3}-4n$$

Solution Steps

Use the distributive property to multiply n by n+2.

$$\left(n^{2}+2n\right)\left(n-2\right)$$

Apply the distributive property by multiplying each term of n^{2}+2n by each term of n-2.

$$n^{3}-2n^{2}+2n^{2}-4n$$

Combine -2n^{2} and 2n^{2} to get 0.

$$n^{3}-4n$$
