Final answer:
The equation (4x² + 2x + 2) + (5x² - 2 - x) simplifies to 9x² + x by combining like terms.
Step-by-step explanation:
To solve the given equation (4x² + 2x + 2) + (5x² - 2 - x), we combine like terms. First, we add the x² terms:
Next, we combine the x terms:
Finally, we combine the constant terms:
Combining all these, we get the simplified expression:
9x² + x
This is now a simpler form that we can work with if further solving is required.
