Answer:

An equation is an expression along with an equal sign (=)

Equations are classified into two main groups'' linear equations and nonlinear equations. Examples of linear equations are as

            x + 13 = 15

            7x + 6 = 0

Nonlinear equations in the variable x are equations whether x appears in the second or higher degrees. They involve cubic and quadratic equations amongst others. For an example:

            5x2 + 3x + 7 = 0 is quadratic equation

            2x3 + 4x2 + 3x + 8 = 0 is cubic equation

The equations'' solution or the values of the variables for that the equations hold is named as the roots of the equation or the solution set.
