Given:
Consider the below picture attached with this question.
The given expression is:
[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]
To find:
The next step.
Solution:
We have,
[tex]\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}[/tex]
Cancel out the common factors.
[tex]=3m-\dfrac{4}{3}-\dfrac{2}{m}[/tex]
Therefore, the correct option is D.
