This expression simplifies to $- 10$ $-10$ .

Begin by distributing the negative to the second binomial. Then you can combine like terms.

$(9 m - 5) - (9 m + 5)$ $(9m - 5) - (9m + 5)$
$9 m - 5 - 9 m - 5$ $9m - 5 - 9m - 5$
$- 10$ $-10$

Remember that $9 m - 9 m = 0$ $9m - 9m = 0$ .

How do you combine like terms in (9m−5)−(9m+5)(9m - 5) - ( 9m + 5)?
