Quadratic Equations: Definition
Quadratic equations can be defined by the name “Quad” which means “Square” In a quadratic equation, one of the variables is squared. This type of equation is also called “Equation of degree 2”.
An algebraic expression of the form: ax² + bx + c = 0, where a ≠ 0, b, c ∈ R is called a quadratic equation.
The solutions of a quadratic equation can be found by equating to 0. The solutions are called ‘roots’ or ‘zeroes’.
