Anyone know where to get factoring formulas (like factoring X^4 - 16)

    Vaxopy, have you considered getting a Ti-89 calculator? They are very usefull in higher math classes. (They are expensive though)

    im in university calculus first year, and no, he didnt cover this ****. it was basically supposed to be a given, but i havent taken math in 2 years so im rusty and have to relearn this =)

    in high school i got 94% in calculus, just cant remember it anymore. all i remember is differentiation, integration, stuff like that, but forgot how to do it the "ancient" way with f(x) - f(a) / x - a

    Why do some people make fun of people who have trouble learning algebra? He's asking a question, school is not a competition...

    It's probably his first year in algebra, I remember I had some painfull experiences with factoring polynomials and such...

    The answer is just (x^2-4)(x^2+4) which factors further to if you want to take it that far..

    (x-2)(x+2)(x+2i)(x-2i)
    That's it.

    It's just using difference of squares twice.

    This stuff is hard to read without MathType or TeX... yuck.

    I am usually accepting of people trying to learn, but sometimes you just need to use your brain BEFORE you ask questions....

    That, my friend, is how you REALLY learn....

    And trust me, i know. I suffered through a chemical engineering degree.
    How do you know how hard the person tried before asking the question?

    The answer is simple once you see it, but you need experience to see it.

    i'm a lurker, but when i saw this thread i couldn't resist.

    Maths (w/o s 4 u americans) is cool. i shoulda took it 4 my degree instead of f00king chemistry. i'm quite good at it [math(s) i mean]. 90%+ is my ave 4 exams.
    i've still got it, i'm so proud.

    but anyway the answer's 3.

    i'm not going to tell u the method but i'll start u off:

    multiply fraction by

    (1+x^1/2)
    (1+x^1/2)

    then expand on top and simplify on bottom

    Buy a TI-89 Calculator. They are the best calculators ever, man. They do all that stuff for you. They integrade, differentiate, solve for zeros, factor, plot, almost anything. I've had mine for 4 years and it really helps with higher math.

    thanks a lot =)

    do you know how difference of squares works?
