Unformatted text preview: little misleading. The title seems to imply that we’re going to
look at equations that involve any radicals. However, we are going to restrict ourselves to
equations involving square roots. The techniques we are going to apply here can be used to solve
equations with other radicals, however the work is usually significantly messier than when
dealing with square roots. Therefore, we will work only with square roots in this section.
Before proceeding it should be mentioned as well that in some Algebra textbooks you will find
this section in with the equations reducible to quadratic form material. The reason is that we will
in fact end up solving a quadratic equation in most cases. However, the approach is significantly
different and so we’re going to separate the two topics into different section in this course.
It is usually best to see how these work with an example. Example 1 Solve x = x + 6 .
Solution
In this equation the basic problem is the square root. If that weren’t there we could do the
problem. The whole process that we’re going to go thr...
