Look at the long division problem shown on the
right complete the division to determine what the
remainder will be.
what is the remainder?

c=2

The remainder is 7.

Step-by-step explanation:

They want you to subtract those last two lines:

----------------------------------------------------

.

2x comes from doing -18-(-20) or -18+20.

Then you bring down the +15 so you have 2x+15 below that last bar in the picture.

Anyways, you then need to find how many times x goes into 2x or what times x gives you 2x?

Hopefully you say 2 here and put that as c.

Now anything you put above the bar has to be multiplied to your divisor so 2(x+4)=2x+8.

We want to see what's left over from subtract (2x+15) and (2x+8). That gives you a remainder of 15-8=7.

Here are my steps for this division:

           4x^3+2x^2-5x+2

         -------------------------------------

 x+4| 4x^4+18x^3+3x^2-18x+15

       -(4x^4+16x^3)

        --------------------------------------

                    2x^3+3x^2-18x+15

                  -(2x^3+8x^2)

                      ----------------------------

                              -5x^2-18x+15

                           -( -5x^2-20x)

                             ----------------------------

                                        2x+15

                                     -(  2x+8)

                                      ------------

                                                7

c=2

The remainder is 7.
