This is what we wish to solve.
We first must recognize that or . So, knowing this, can you finish up?
When dealing with absolute value, you have to be aware of the folling fact-that So, therefore can have 2 different values, but the corresponding value of , or will have only one. So knowing that....
We've got to set up different possibilities for the given expressions.
So, with this, can you take it from here?
