Rational Equations

Rational Equations are equations that contain rational expressions.

Below is an example of a rational equation:

Figure 1.

We start by simplifying:

Figure 2.

Here, the rational equation has been simplified. Now it is quadratic form, and we can use the quadratic equation to solve for "x":

Figure 3.

Our two roots are x = 2.39 and x = -1.39.
