===Pure Quadratic Equation & Adfected Quadratic Equation===
Quadratic equation,in the form ax^2+ bx +c, is termed as quadratic expression and the equation of the form ax^2+ bx +c=0 , a≠0 is called quadratic equation in x. This equation is also known to be pure quadratic equation if the value of b is zero i.e. b=0. Otherwise it is said to be affected. The letters a, b, and c are called coefficients: and c is the constant coefficient.
