Subtract the following polynomials, then place the answer in the proper location on the grid. write your answer in descending powers of x.
subtract 2x^2 - 6x - 4
from 4x^2 - 4x + 3.

You can do it in two ways, its either vertical or horizontal and it will look like this, 
The 1st way: 2x^2 - 6x - 4
                     -4x^2 - 4x + 3
 
or  2x^2 - 6x - 4 -( -4x^2 - 4x + 3) = 0
This is the 2nd way

The answer is still 2x^2 + 2x + 7 = 0. 

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b

Ithink it’s a as the answer.
