Solve m(m+2)(m-8)

$$m ( m + 2 ) ( m - 8 )$$

Evaluate

$$m\left(m-8\right)\left(m+2\right)$$

Solution Steps

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

$$\left(m^{2}+2m\right)\left(m-8\right)$$

Apply the distributive property by multiplying each term of m^{2}+2m by each term of m-8.

$$m^{3}-8m^{2}+2m^{2}-16m$$

Combine -8m^{2} and 2m^{2} to get -6m^{2}.

$$m^{3}-6m^{2}-16m$$

Expand

$$m^{3}-6m^{2}-16m$$

Solution Steps

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

$$\left(m^{2}+2m\right)\left(m-8\right)$$

Apply the distributive property by multiplying each term of m^{2}+2m by each term of m-8.

$$m^{3}-8m^{2}+2m^{2}-16m$$

Combine -8m^{2} and 2m^{2} to get -6m^{2}.

$$m^{3}-6m^{2}-16m$$
