Guro Posted September 15, 2009 Report Share Posted September 15, 2009 I was thinking the same thing as Catie, haha Didn't quite get how you got (x+1) there ;p But thank you so much Ross! :D You are the best! Quote Link to comment Share on other sites More sharing options...
captain.obvious Posted September 15, 2009 Report Share Posted September 15, 2009 hahabut im still confused on how you got that... it looks like it just appeared out of nowhere As long as you do it to both top and bottom you can add w/e you want. (4/5) is the same if you multiply each one by a number, like 2... (4*2)/(5*2)=8/10=4/5 Quote Link to comment Share on other sites More sharing options...
Ross Posted September 15, 2009 Report Share Posted September 15, 2009 hahabut im still confused on how you got that... it looks like it just appeared out of nowhere Well the middle denominator is a difference of two squares (x^2 -1) so that can also be written as (x-1)(x+1). And (x+1) is in the denominator of fraction three. So you multiply fraction three by (x-1)/(x-1) so that both fractions two and three have the same denominator and can be added together.
