- Introduction and Standard Form of a Quadratic Equation - ax
^{2}+ bx + c = 0, (a ≠ 0)

Standard form of quadratic equation

The equation involving one variable and having 2 as the maximum index of the variable is called the quadratic equation.

General form is ax^{2} + bx + c = 0

In ax^{2} + bx + c = 0, a, b, c are real numbers and a≠ 0.

ax^{2} + bx + c = 0 is the general form of quadratic equation.

Activity : Complete the following table

Ex. (1)3x^{2} - 5x + 3 = 0

(1) In the equation 3x^{2} - 5x + 3 = 0, x is the only variable and maximum index of the variable is 2

∴ It is a quadratic equation.

The equation involving one variable and having 2 as the maximum index of the variable is called the quadratic equation.

General form is ax^{2} + bx + c = 0
