Calculate the difference:
(9x
3 + 4x
2 - 6x + 1) - (9x
3 + 54x)
Multiply each term in 9x
3 + 54x by -1
-1 x (9x
3 + 54x) = -9x
3 - 54x
Collect all of our terms:
9x
3 + 4x
2 - 6x + 1 - 9x
3 - 54x
Now group all of our x
3 terms:
9x
3 - 9x
3 = 0x
3
Now group all of our x
2 terms:
4x
2
Now group all of our x terms:
- 6x - 54x = -60x
Now group all of our constant terms:
1
Build our answer:
+ 4x2 - 60x + 1
