    Re: rregarding studying

    Huh? Is this a question? Before, it looked like you had the question:

    $\sqrt{x+15}+\sqrt{x} = 15$

    If you are trying to solve for $x$, I recommend multiplying both sides by the conjugate: $\sqrt{x+15}-\sqrt{x}$

    to get:

    $(x+15)-(x) = 15\left(\sqrt{x+15}-\sqrt{x}\right)$

    Now, you have two equations:
    $\sqrt{x+15}+\sqrt{x} = 15$
    $\sqrt{x+15}-\sqrt{x} = 1$

    Add them together to get
    $2\sqrt{x+15} = 16$

    Now, this is easy to solve, and we find $x = 49$.

    Slip Eternal,skeeter
    The Question which I am trying to asking is :-
    When we are doing self studying ,What is a strategy we should follow while Reading Math Textbook Chapter?
    Example-3 D Geometry
    so in this chapter
    we read introduction,summary,questions to get idea what chapter is about
    then finally skimming and scanning of concepts in detail.
    Then do quiz after reading and practicing chapter in order not to forgot concepts.
    Is this correct.

    Re: rregarding studying

    People have different ways of learning. No one can tell you what is the "correct" way for you to study. I had friends in college that didn't even bother to purchase the required text for the course ... they went to the library and researched concepts from various sources (this was in the days of slip-sticks, large spiral notebooks, and boxes of pencils).

    If what you stated works for you, then do it. Given the ready availability of many resources on the web, I personally would not limit study to a single text.
