Lesson 5

Lesson 5 Summary

In this lesson you investigated the following question:

• How do you solve problems by modelling situations using radical equations?

You learned to model a variety of situations using radical equations. You learned that making a diagram is often helpful in getting the equation to match the situation.

You also learned that equations can be solved even if the variable needed is part of a radicand. Equations can be solved by rearranging and squaring both sides of the equation, or by substituting the values into the equation as it is.
