Step-by-step explanation:

Step 1: Define

Identify

f(x) = 3x² - x + 5

g(x) = 2x - 3

Step 2: Find f(x) - g(x)

1. Substitute in function values:                                                                          f(x) - g(x) = 3x² - x + 5 - (2x - 3)
2. [Distributive Property] Distribute negative:                                                    f(x) - g(x) = 3x² - x + 5 - 2x + 3
3. [Subtraction] Combine like terms (x):                                                              f(x) - g(x) = 3x² - 3x + 5 + 3
4. [Addition] Combine like terms:                                                                        f(x) - g(x) = 3x² - 3x + 8
