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.
