3x +3(x-10) = 360
3x +3x-30 =360
6x-30 =360
6x=390
X = 390/6 = 65
65-10 =55

To find:
The division of the polynomial.
Solution:
The division in given in the image below:
Thus, the result is:

Option D is correct.
To do this, you must use the order of operations.
3·2=6
6+4=10
Now to solve (-)x.
Since -x comes in front of 4, you must make your equation:
-x+10
Nothing is written for x, so now, you have the answer.
-x+10
We are given

we can use distribute property
Distributive property:

so, we can write it as


now, we can multiply terms
and we get
