Introduction to Quadratic Equations Formula

Introduction to Quadratic Equations:

In this section let me help on quadratic equation formula. A quadratic functions in the variable of x is an equations of the general form ax2 + b x + c = 0, Where "a","b","c" are real numbers, a not equal to Zero. 2x2 + x – 300 = 0 is a quadratic equations.

The Simplifying Quadratic equations, the general form is ax2 + bx + c, where "a", "b", and "c" are just numbers; they are known as the "numerical coefficients". The Formula is derived by the process of completing the square.

Example:

Solve (x + 1)(x – 3) = 0.


solution:-

(x + 1)(x – 3) = 0
x + 1 = 0 or x – 3 = 0
x = –1 or x = 3


The solution is x = –1, 3
