A quadratic equation is a polynomial of the second degree. In other words, one of its terms possesses an exponent of 2. A quadratic equation usually consists of three terms. Here is the standard form of a quadratic equation:

ax^{2} + bx + c = 0

In such an equation, the constant a cannot be equal to 0, because then the variable x is also 0. As already mentioned, the degree of the quadratic equation is based on the value of the exponent for the variable x, which is 2. On the other hand, the constants c and b can be zero.

To solve quadratic equations, you can employ a set of techniques. Using this set of techniques provides a much easier way to solve quadratic equations than if you approach them intuitively. To understand how to ...
