### What is Meant by 2nd Degree Equation?

In Maths, the quadratic equation is called a second-degree equation. A quadratic equation is defined as the polynomial equation of the second degree with the standard form **ax ^{2}**

**+ bx+ c =0,**where a≠0, The solutions obtained from the equation are called roots of the quadratic equation.

Here

x represents the unknown variable

a, b, c represents the constant (also known as quadratic coefficients)

In case, if a = 0, then the equation is called the linear equation.
