Answer:
f(x)g(x) = x³ - 9x² + 9x - 81
General Formulas and Concepts:
Distributions - Expanding with FOIL (First, Outside, Inside, Last)
Explanation:
Step 1: Define
f(x) = x² + 9
g(x) = x - 9
Find f(x) · g(x)
Step 2: Find
- Set up expression: f(x)g(x) = (x² + 9)(x - 9)
- Expand (FOIL): f(x)g(x) = x³ - 9x² + 9x - 81
