Calculus Intro

  1. Mar 10, 2013 #1
    Solve x/ x-2 >2 by first rewriting it in the form P(x) / Q(x) >0


    How do I go about first rewriting it into that form?

    I assume you mean , Solve x/(x-2) > 2 .

    Parentheses are important. What you wrote literally means [itex]\displaystyle \ \ \frac{x}{x}-2>2\ .[/itex]


    To get started on the problem, add 2 to both sides.

    Then make the expression on the left side into one rational expression.

    Yes sorry

    X/ (X-2) > 2


    and form (P(x))/(Q(x)) > 0

    See the little bit I added to my previous post after you quoted it.
