ã6(2ã6 - ã5)

How do you get 12-ã30?

I keep getting a way different answer:\ Btw not sure if the radicals will show up.

    If its possible, could you please do this on paint or something for me, and upload it so I can see how exactly you solved this, because explaining over Jiskha, will probably be hard for me to understand as I will not be able to visualize certain steps.

    √6(2√6 - √5)

    To multiply two radicals, just keep the radical sign and then multiply the two numbers inside.
    e.g. √5 x √7 = √35
    and then of course √6 x √6 = √36 = 6
    when you multiply a square root by itself, you get that number
    √13 x √13 = 13

    so back to our question, let's just expand it
    = 2√36 - √30
    = 2(6) - √30
    = 12 - √30
