Simplifying the Expression (2x^2 + 5) + (-x^2 + 4)
This expression involves adding two polynomials. To simplify, we can combine like terms.
1. Identify Like Terms:
- x² terms: We have 2x² and -x²
- Constant terms: We have 5 and 4
2. Combine Like Terms:
- x² terms: 2x² - x² = x²
- Constant terms: 5 + 4 = 9
3. Final Simplified Expression:
By combining the like terms, we get the simplified expression: x² + 9
Therefore, (2x² + 5) + (-x² + 4) simplifies to x² + 9.
