What Is a Quadratic Expression?
A quadratic expression always takes the form ax² + bx + c, where:
- a, b, and c are constants (real numbers),
- a ≠ 0, ensuring the expression is genuinely quadratic (not linear).
For our simplified expression 8x² – 18x + 9, we identify:
- a = 8
- b = –18
- c = 9
Why Simplification Matters
Simplifying expressions:
- Reduces errors in calculations.
- Clarifies the function’s behavior.
- Facilitates graphing, solving equations, and identifying key features like roots, vertex, and axis of symmetry.
