Multiply through by 

However since we are multiplying thorugh by a variable
we will have to check our answers at the end.





x = ±2

We get two solutions +2 and -2, but we must check
them both in the original equation since we multiplied 
through by a variable:

Substitute +2 for x





Division by 0 is not defined.  So we can rule out +2

Substitute -2 for x






So -2 is the only solution.
