    OH I NEEDED TO STATE THE RESTRICTIONS for this question if there were any but I dont know what step to get the restrictions from, anyone have any ideas? :smile:

    The restriction would be any value of x that you can put into the original equation to make the solution undefined. For example, if you have an equation:
    1/x = 6,

    x cannot equal zero or the operation is undefined. What would that make the restrictions in your case?

    are the restrictions x cannot = 1 or -1? or are there more?
