Study Notes
Quadratic Equations Overview
- Quadratic equations are polynomial equations of the form ( ax^2 + bx + c = 0 ), where ( a ), ( b ), and ( c ) are constants and ( a \neq 0 ).
- If ( a = 0 ), the equation becomes a linear equation, losing its quadratic nature.
Solutions of Quadratic Equations
- Solutions of a quadratic equation are referred to as roots or solutions.
- Typically, a quadratic equation can have zero, one, or two solutions.
Types of Solutions
- Two distinct real solutions occur when the discriminant (( b^2 - 4ac )) is positive.
- One real solution occurs when the discriminant is zero, indicating a perfect square.
- No real solutions occur when the discriminant is negative, leading to complex solutions.
Characteristics of Solutions
- If a quadratic equation has only one solution, it indicates that the graph touches the x-axis at a single point (vertex), known as a double root.
Quadratic Equations Classification
- An equation must have the highest degree of 2 to be classified as a quadratic equation.
- Equations featuring variables raised to powers greater than 2, or with variable degrees of 1, do not qualify as quadratic equations.
