Calculate the difference:
(x
2 - 6x + 8) - (x
2 - 3x)
Multiply each term in x
2 - 3x by -1
-1 x (x
2 - 3x) = -x
2 + 3x
Collect all of our terms:
1x
2 - 6x + 8 - 1x
2 + 3x
Now group all of our x
2 terms:
1x
2 - 1x
2 = 0x
2
Now group all of our x terms:
- 6x + 3x = -3x
Now group all of our constant terms:
8
Build our answer:
- 3x + 8
