Answer:
= -2x² - y² - 3z²
Step-by-step explanation:
4x² + 3y² - 5z², - 6x² - 4y² + 2z²
= 4x² + 3y² - 5z² + (- 6x² - 4y² + 2z²)
= 4x² + 3y² - 5z² - 6x² - 4y² + 2z²
= 4x² - 6x² + 3y² - 4y² - 5z² + 2z²
= -2x² - y² - 3z²

Answer:
-2x^2-y^2-3z^2
Step-by-step explanation:
4x^2+(-6x^2)=4x^2-6x^2=-2x^2
3y^2+(-4y^2)=3y^2-4y^2=-y^2
-5z^2+2z^2=-3z^2
