    What is your question? You've done the substitution correctly, so you see how the x's cancel. What is the problem?

    Lower limit is [tex]0[/tex]. Why I may cancel x's?

    Because the functions are defined on intervals not containing the point 0, that's why you can have the x in the denominator and simplify it through.
