well ill go through the whole question up to where i am (not very far) to make sure there were no prior errors, but i cant simplfy past where i am (maybe i just cant see it)(adsbygoogle = window.adsbygoogle || []).push({});

Differentiate and simplify

.........(1-x)^4

f(x) = --------

...........1-4x

f'(x) = [4(1-x)^3(-1)](1-4x) - (1-x)^4(-4)

.........-----------------------------------

..........................(1-4x)^2

......= (-4)(1-x)^3 - (1-x)^4(-4)

.........------------------------- note: i cancelled the (1-4x) on top

.....................(1-4x) with one from the bottom

......= stuck (i tried common factoring on top but still cant get it)

any help will be GREATLY appreciated (last question on assignmentand driving me crazy)

sorry bout the formating, cant seem to get it right (hence the periods)
