Question

The first step when dividing 9m2 − 4m − 6 by 3m is shown. Which could be the next step? 3m − − 3m − − 3m − − 3m − −

Answer 1

Given:

Consider the below picture attached with this question.

The given expression is:

$\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}$

To find:

The next step.

Solution:

We have,

$\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}$

Cancel out the common factors.

$=3m-\dfrac{4}{3}-\dfrac{2}{m}$

Therefore, the correct option is D.
