Study Notes
Quadratic Equation
- The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants, and a ≠0.
Roots of a Quadratic Equation
- The formula to find the roots of a quadratic equation is x = (-b ± √(b^2 - 4ac)) / 2a.
Discriminant of a Quadratic Equation
- The discriminant of a quadratic equation is b^2 - 4ac, and it is used to determine the nature of the roots:
- If the discriminant is greater than 0, the roots are real and distinct.
- If the discriminant is equal to 0, the roots are real and identical.
- If the discriminant is less than 0, the roots are complex and distinct.
