- We solve the simple inequality (x-1)(x-2)>0.
-
- If Cases 1 and 2 (with change of breakdown) have been reduced to icons,
- then expand them. We start by examining these.
-
- After the first ENTER we broke down the problem into cases (SHIFT+y) and
- solved each of them separately.
- We choose to enter the solution in a single window. To do this we press
- SHIFT+x and two new windows appear. We enter the result in the first window,
- close the second, and press ENTER.
-
- We are now in the window Breakdown 1: Case 1 and we can press Answer.
-
- This is not as hard as it looks. Close the individual windows and solve the
- problem from the beginning, using the description to help you. Of course,
- when you start working the names of the windows will be slightly different.
-
- NB We can only combine cases for which we have not yet given an answer.
-
- By clicking on the tabs at the top we can see all the transformations
- we have carried out.
