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 a ≠ 0.
- The vertex form of a quadratic equation is $f(x) = a(x - h)^2 + k$, where (h, k) is the vertex of the parabola.
Discriminant of a Quadratic Equation
- The discriminant of a quadratic equation $ax^2 + bx + c = 0$ is denoted by D and is equal to $b^2 - 4ac$.
- The discriminant determines the number of solutions of the quadratic equation.
