Answer 1

Answer:

f(x) = (x - 7)² - 14

General Formulas and Concepts:

Pre-Algebra

• Equality Properties

Algebra I

• Standard Form: ax² + bx + c = 0
• Vertex Form: f(x) = a(bx - c)² + d
• Completing the Square: (b/2)²

Step-by-step explanation:

Step 1: Define

f(x) = x² - 14x + 63

Step 2: Rewrite

1. Separate:                              f(x) = (x² - 14x) + 63
2. Complete the Square:         f(x) = (x² - 14x + 49) + 63 - 49
3. Simplify:                                f(x) = (x - 7)² - 14
