Answer:
-x² - 9 is your simplified form
Step-by-step explanation:
Combine terms with the same amount of variables.
(2x² - 5) - (3x² + 4)
First, distribute the negative sign to all terms within the second parenthesis
(2x² - 5) - 3x² - 4
Combine like terms
2x² - 3x² = -x²
-5 - 4 = -9
-x² - 9 is your simplified form
