Question 1127780: I am struggling with this section. If you could show me step by step solving of a similar problem, I will try to solve my problem on my own. Thank you. The question reads as follows. Solve the following equation. Express all answers in interval notation....
+%28-x%29+%2F+%28x%5E2+-1%29++%3C++0+

+%28-x%29+%2F+%28x%5E2+-1%29++%3C++0+ ...eliminate negative sign, factor denominator
+x%2F+%28%28x+-1%29%28x%2B1%29%29++%3E++0+..............since denominator cannot be equal to 0, find values of x that will make denominator equal to 0
%28x+-1%29%28x%2B1%29=0 if x=1 or x=-1; so, we will exclude these values from the solutions set
next,numerator +x+%3E++0+
solutions:

+-1%3Cx%3C0+ or +x+%3E++1+

(1, infinity)
(-1, 0)
