Subtract 21x^3-47x^2-22x+24 and 21x^3-12x^2

Subtract 21x^3-47x^2-22x+24 and 21x^3-12x^2 Image to Crop

Calculate the difference:
(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 + 12x²

Now group all of our x³terms:
21x³ - 21x³ = 0x³

Now group all of our x²terms:
- 47x² + 12x² = -35x²

Now group all of our x terms:
-22x

Now group all of our constant terms:
24

- 35x² - 22x + 24

- 35x² - 22x + 24
