Equation simplification

    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!

    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
