(21x3 - 47x2 - 22x + 24) - (21x3 - 12x2)
Multiply each term in 21x3 - 12x2 by -1
-1 x (21x3 - 12x2) = -21x3 + 12x2
Collect all of our terms:
21x3 - 47x2 - 22x + 24 - 21x3 + 12x2Now group all of our x3 terms:
21x3 - 21x3 = 0x3
Now group all of our x2 terms:
- 47x2 + 12x2 = -35x2
Now group all of our x terms:
-22x
Now group all of our constant terms:
24
