# How do you simplify 9(-2c)(3d)?

Jan 28, 2017

See the entire simplification process below:

#### Explanation:

First, rewrite the expression to group common terms, in this case constants and variables:

$\left(9 \times - 2 \times 3\right) \left(c d\right) \to$

Now, multiply constants and combine with the variables:

$\left(- 18 \times 3\right) \left(c d\right) \to$

$- 54 \left(c d\right) \to$

$- 54 c d$
