## Enter two polynomials to perform operations on:

Calculate the difference of (-3x + 8) - (-3x + 9)

Since we are subtracting, we need to multiply each term in -3x + 9 by -1

-1 x (-3x + 9) = 3x - 9

## Collecting all of our terms, our resulting expression is:

-3x + 8 + 3x - 9

Now group all of our x terms:

-3x + 3x = 0x

Now group all of our constant terms:

8 - 9 = -1

## Now take our groupings of terms by powers and constants and form our answer:

** - 1**
