Study Notes
Quadratic Equations
- The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable.
Quadratic Equation Components
- The discriminant of a quadratic equation is b^2 - 4ac, which determines the nature of the roots of the equation.
Solving Quadratic Equations
- The quadratic formula is x = (-b ± √(b^2 - 4ac)) / 2a, which is used to find the roots of a quadratic equation.
