Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 3x² - x + 5
g(x) = 2x - 3
<u>Step 2: Find f(x) - g(x)</u>
- Substitute in function values: f(x) - g(x) = 3x² - x + 5 - (2x - 3)
- [Distributive Property] Distribute negative: f(x) - g(x) = 3x² - x + 5 - 2x + 3
- [Subtraction] Combine like terms (x): f(x) - g(x) = 3x² - 3x + 5 + 3
- [Addition] Combine like terms: f(x) - g(x) = 3x² - 3x + 8
