Calculator not factoring properly? When I type; ((y^2/11) - (11/(4y^2))^2 on my calculator it gives me; ((4y^4 - 121)^2)/1936y^4 Any idea why? If I add one to that it gives me some mass complicated fraction, where what I want is; y^4/121 + 121/(16y^4) + 1/2

    Sorry, I typed it wrong. Square everything. (((y^2/11) - (11/(4y^2)))^2 \[((y^2/11) - (11/(4y^2))^2\]

    There. If you look at that Wolfram link the answer that I want is the third alternative. IT is giving me the first alternative in both Wolfram and my Calculator. Any ideas how to change that?

    you said you want + 1/2, not - 1/2

    If I added 1 to that it would give + 1/2. Was just a different way of writing the problem, but either way gives me the same form.

    OK, damn. Too bad. My calculator just keeps giving really nasty fractions. I guess I can just use wolfram to check and use the alternative forms.

    wolfs got these tabs that if you hover over the ... bottom left corner of something itll give you the option to have a copyable setup

    Oh, awesome! I've wanted to copy in wolfram so often, never knew how. Thanks again for your help!
