-4 - 6

Step-by-step explanation:

First you have to add the two polynomials.  Write the first equation then line up the second equation below the first making sure to keep the columns correct.   goes in one column, x goes in the next column and the whole numbers go in the last column.  Also be sure to have the correct signs of those columns.  It should look like this:

                      4   -   x   +   1

PLUS             -6   +   x   -   4

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

                      -2   +  0   -   3

Note that the middle x turns to 0 because you're subtracting 1x from 1x which is 0.

You can now write the SUM as   -2 - 3

Now they want to know what twice this sum is so multiply it by 2

                          2 ( -2 - 3)  =  -4  -  6
