Answer:

-3x² - 10x - 16 r.
(-29)/(x-2)

Explanation:

You can easily do this through synthetic division:

First step is to get all the numeric coefficients of the expression and write them down. Don't forget to bring their signs along with them.

-3- 4+ 4x +3

| -3 -4 +4 +3

|______________

Next we find the root that is associated with the divisor:

x - 2 = 0

x = 2

We use this and put it outside:

2 | -3 -4 +4 +3

|______________

Okay now we bring down the first coefficient:

2 | -3 -4 +4 +3

|______________

-3

Then we multiply it by the root and put the product under the next coefficient:

2 x - 3 = -6

2 | -3 -4 +4 +3

| -6

-3

Then we add them:

2 | -3 -4 +4 +3

| -6

-3 -10

Do the same steps until the end:

2 | -3 -4 +4 +3

| -6 -20 -32

-3 -10 -16 -29

Now that you have that, remember that since the divisor is in the 1st degree, quotient will have a degree will be one degree below as well.

-3x² - 10x - 26

Your last coefficient is going to be your remainder:

-3x² - 10x - 16 r.
(-29)/(x-2)
