Answer:
Explanation:
To subtract (x² + 3x - 7) - (3x² - 5x + 3), we need to distribute the negative sign to the second polynomial and then combine like terms.
(x² + 3x - 7) - (3x² - 5x + 3) = x² + 3x - 7 - 3x² + 5x - 3
Now we can combine like terms:
= (-3x² + x²) + (3x + 5x) + (-7 - 3)
= -2x² + 8x - 10
Therefore, the answer is -2x² + 8x - 10 in standard form.
