The difference is 14
Step-by-step explanation:
To subtract two polynomials
- Arrange the terms of the two polynomials from the greatest power
- Subtract a from be means b - a, so put the polynomial comes after word from at first
- Subtract the like terms
∵ 3x² + 4x - 5 is subtract from 7x² + x + 9
- Put the the polynomial comes after word from at first
∵ (7x² + x + 9) - (3x² + 4x - 5)
- Subtract the like terms
∴ (7x² - 3x²) + (x - 4x) + (9 - -5) =
∴ 4x² + (-3x) + (9 + 5) =
∴ 4x² - 3x + 14 is the result
∵ You will subtract 4x² - 3x from the result
∴ (4x² - 3x + 14) - (4x² - 3x) =
- Subtract the like term
∵ (4x² - 4x²) + (-3x - -3x) + 14 =
∴ 0x² + (-3x + 3x) + 14 =
∴ 0x² + 0x + 14 = 14
∴ The difference = 14
The difference is 14
