Answer:
f(x) + g(x) = 7x² - 4x + 2
General Formulas and Concepts:
Algebra I
Explanation:
Step 1: Define
f(x) = 5x² - 3x - 1
g(x) = 2x² - x + 3
Step 2: Find f(x) + g(x)
- Substitute: f(x) + g(x) = 5x² - 3x - 1 + 2x² - x + 3
- Combine like terms (x²): f(x) + g(x) = 7x² - 3x - 1 - x + 3
- Combine like terms (x): f(x) + g(x) = 7x² - 4x - 1 + 3
- Combine like terms (Z): f(x) + g(x) = 7x² - 4x + 2
