Answer 1

Answer:

-4$x^{2}$ - 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.  $x^{2}$ 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$x^{2}$   -   x   +   1

PLUS             -6$x^{2}$   +   x   -   4

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

                      -2$x^{2}$   +  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$x^{2}$ - 3

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

                          2 ( -2$x^{2}$ - 3)  =  -4$x^{2}$  -  6
