Equation simplification

    Hi,

    Thanks for taking the time to look at my problem.

    I'm following a worked example in a text book and I have come to a line of simplification which I just can't see how/what they've done? I've attached a .jpg showing the two lines of simplification.

    Making this simplification helps with integration later on but that's not relevant to this...

    Any help would be much appreciated!

    Thanks

    Simon

    [tex](L-x)=L\left(1-\frac{x}{L}\right)=L\left(2-\frac{x}{L}-1\right)=L\left(2\left(1-\frac{x}{2L}\right)-1\right)[/tex]

    Hello Gerenuk,

    Brilliant..... Thank you very much indeed, I'd spent all day banging my head on the desk over this. I kept trying to expand everything out and group back together again which was pretty stupid I guess....

    Thank you again for your help
