Topics in Quadratic Equations
Introduction and Standard Form
- A quadratic equation is of the form ax² + bx + c = 0 where a, b, c are real numbers and a ≠ 0
- The standard form arranges terms in descending order of powers
- Real-life problems often lead to quadratic equations (area problems, motion problems, etc.)
Solution by Factorization Method
- Factor the quadratic expression ax² + bx + c into two linear factors
- Use the zero product property: if AB = 0, then A = 0 or B = 0
- Split the middle term method is most commonly used for factorization
Quadratic Formula Method
- Universal method that works for all quadratic equations
- Derived by completing the square method
- Gives exact roots even when they are irrational
Completing the Square Method
- Transform ax² + bx + c = 0 into the form (x + p)² = q
- Useful for understanding the geometric interpretation of quadratic equations
- Helps in finding the vertex form of parabolas
