Question

F(x) = x2+9
g(x) = X-9
Find f(x)*g(x).

Answer 1

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

1. Set up expression: f(x)g(x) = (x² + 9)(x - 9)
2. Expand (FOIL): f(x)g(x) = x³ - 9x² + 9x - 81
