Hey!

First, let's write the problem.
[tex]3m^2+4m-6m^2[/tex]
Although it's not necessary, we could group like terms together.
[tex]=3m^2-6m^2+4m[/tex]
Add like terms. [tex]3m^2-6m^2=-3m^2[/tex]
[tex]=-3m^2+4m[/tex]

This tells us that,
[tex]3m^2+4m-6m^2=-3m^2+4m[/tex]

Thanks!

3m² + 4m - 6m²

Add like terms.

(3m² - 6m²) + 4m

Simplify.

Because both numbers inside of the above parenthesis has m² in it, we can simplify them with one another.

-3m² + 4m

~Hope I helped!~
