Question

How do you simplify `-3m - 9( 6m + 5)`?

Answer 1

See a solution process below:

Explanation:

First, expand the term within parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis. Be careful to manage the signs of the individual terms correctly:

`-3m - color(red)(9)(6m + 5) =>`

`-3m - (color(red)(9) xx 6m) - (color(red)(9) xx 5) =>`

`-3m - 54m - 45`

Now, combine the like terms:

`(-3 - 54)m - 45`

`-57m - 45`
