    BTW,, the fractional expression can be simplified by factoring out x in the numerator.

    I know. I just want to know how to solve for the limit using substitution I know x can't be 0, but that's basically all I know.

    After you factor X from the numerator, you should be able to cancel a factor of one or x/x

    Then you'll be left With an expression Where you can use substitution to find the limit.

    How do I find the limit? That's the part I don't know how to do.

    Now that you have the expression x-1 Take the limit as x goes to zero for x-1
