Definition of Quadratic Equation
A quadratic equation is a special type of algebraic equation in which the highest power of the variable (usually \(x\)) is \(2\).
So, \(x^2 - 2x + 5 = 0\) is a quadratic equation, but \(x^4 - 17x^2 + 15 x - 9 = 0\) is not.
Quadratic equations are usually written
For example, \(3x^2 + 17 x - 54 = 0\) is a quadratic equation.
Quadratic equations may have \(0\), \(1\) or \(2\) solutions.
