The answer would be 3x^2-13+50/x+4

Step-by-step explanation:
You can use synthetic division to solve this.
How you do synthetic division you have to take the number on x+4 and change its sign

Which is -4

Then you take A B and C (in this case A B and C is 3, -1, and -2)

To do synthetic division you bring the 3 down and multiply it by -4 and add the answer to the -1

Then you have 3-13 which you can change into 3x-13. For this specific problem it has a remainder.

You find the remainder by going back to your -4 and multiply it by the -13 (which is 52 because a negative times a negative equals a positive) and add the 52 to -2 which is 50.

So your final answer is 3x-13+50/x+4

I’m sorry if this was confusing written out like this. If you want to learn how to do synthetic division search it up.

Hope this helps
