Final answer:
To subtract x² - 6x from 5x² - 7x - 105x² - 7x - 10, combine like terms and distribute the negative sign.
Step-by-step explanation:
To subtract x² - 6x from 5x² - 7x - 105x² - 7x - 10, we can combine like terms. First, combine the x² terms: 5x² - 105x² = -100x². Then, combine the x terms: -7x - 7x = -14x. Finally, subtract x² - 6x from the combined terms: -100x² - 14x - (x² - 6x). To subtract, distribute the negative sign: -100x² - 14x - x² + 6x. Combine like terms again: -101x² - 8x.
