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 can't simplfy past where i am (maybe i just can't see it)
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 canceled the (1-4x) on top
.....(1-4x) with one from the bottom
...= stuck (i tried common factoring on top but still can't get it)
any help will be GREATLY appreciated (last question on assignmentand driving me crazy)
sorry bout the formating, can't seem to get it right (hence the periods)
