Quadratic Polynomial

A quadratic polynomial is a polynomial of degree 2. 

A single-variable  quadratic polynomial has the form a.x²+b.x+c. where a ≠ 0

Quadratic Equation

An equation involving a quadratic polynomial is called a quadratic equation like a.x²+b.x+c.=0

 A closed-form solution known as the quadratic formula exists for the solutions of an arbitrary quadratic equation.

Quadratic Formula

The quadratic formula helps us solve any quadratic equation. 

First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. 

Then, we plug these coefficients in the formula:

x= (-b±√(b²-4ac))/(2a)
