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.

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.
