Answer:

2c

Step-by-step explanation:

8c^3           2c^2

------------ ÷ -------------

6 (c+d)       3c+3d

Factor the 3 out of the denominator in the last  term

8c^3           2c^2

------------ ÷ -------------

6 (c+d)       3(c+d)

Since this is division, we can use copy dot flip

8c^3          3(c+d)

------------ * -------------

6 (c+d)       2c^2

We can cancel the (c+d) in the denominator on the left and the numerator on the right

8c^3          3

------------ * -------------

6                2c^2

We can cancel c^2 from the numerator on the left (leaving a c) and the denominator on the right

8c             3

------------ * -------------

6                2

24c

-----

12

24/12 = 2  so we are left with

2c
