Study Notes
Quadratic Equations
- Main focus: Quadratic equations and their properties
Definition and Types of Solutions
- Quadratic equations are equations of the form ax^2 + bx + c = 0, where a, b, and c are real numbers, and a ≠ 0
Number of Solutions
- A quadratic equation can have at most two solutions
- If all coefficients of a quadratic equation are real numbers, possible types of solutions are:
- Two distinct real solutions
- One repeated real solution
- Two distinct complex solutions
Roots of a Quadratic Equation
- The values of x that satisfy a quadratic equation are called roots or solutions of the equation
Special Case: Only One Solution
- If a quadratic equation has only one solution, it is called a repeated root or a double root
Special Case: a = 0 and b ≠ 0
- If a = 0 and b ≠ 0 in the standard form of a quadratic equation, the equation is a linear equation
