Since a linear equation has the form ax + b = 0 (or y = ax + b), we know that a nonlinear equation does not have this form.

We’ll also look at nonlinear systems, along with examples to make the concepts clear. In this article, we’ll take a look at nonlinear equations, what they are, and how to solve them. You can sometimes solve these systems to find one or more solutions (although some have no solution). Of course, you can take two or more nonlinear systems together in order to get a nonlinear system. They can also contain rational, exponential, and logarithmic functions. Nonlinear equations can contain polynomials with quadratic, cubic, and higher order terms. It cannot be reduced to the forms ax + b = 0 or y = ax + b. So, what are nonlinear equations? A nonlinear equation has at least one term that is not linear or constant. Since they are pretty common, it helps to know about nonlinear equations and how to solve them.

Nonlinear equations appear often in algebra, calculus, and physics (for example, when solving problems that involve gravity or acceleration).
