Answer:
(f - g)(x) = 3x² - 2x - 6
General Formulas and Concepts:
Pre-Algebra
Algebra
- Combining like terms
- Standard Form: ax² + bx + c = 0
Step-by-step explanation:
Step 1: Define
f(x) = 3x² - 2
g(x) = 2x + 4
(f - g)(x) is f(x) - g(x)
Step 2: Find
- Substitute: (f - g)(x) = 3x² - 2 - (2x + 4)
- Distribute -1: (f - g)(x) = 3x² - 2 - 2x - 4
- Combine like terms: (f - g)(x) = 3x² - 2x - 6
