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
