X^3/2 - 2x^-1/2 + x^1/2 Help! Factoring!

vendredi 1 novembre 2013

I'm looking to factor this...





X^3/2 - 2x^-1/2 + x^1/2



The text book offers the solution 1-x ^4/3



No idea how to get this result. I got X ^-3/2 (x-1)^2

I would like it if someone could shed light on how to factor x^-3/2 from things like 2x ^1/2

I assume you just keep the equation balance, so if you re-distribute everything, it reverts to the original.



I would like to know how you get the answer too.



Thanks so much!
