Solve:

### Solution

We draw three number lines: one for the numerator, the second one for the denominator and the third one for the quotient. The first line shows that is equal to for , positive for and negative for .

----------------- (+1) ++++ x-1

----- (-1) +++++++++++ x+1

+++ (-1) ----- (+1) ++++ quotiënt

From this we can determine the sign of the quotient of both linear functions because:

- / - = +

+ / + = +

+ / - = -

- / - = +

and find:
