Help with Chain Rule Question, Differentiating?
A curve has the equation:
y=4-(2/(2x-1)^(3)) -x
(A) Find DY/DX.
The answer is
= (8/(2x-1)^3) -1
My answer is = (8/(2x-1)^3) -2
Can you please show me how you can get the right answer (-1 at the end rather than -2)?
Thanks

frame the question as
y = 4- 2 (2x-1)^-3 -x taking the denominator to the numerator by raising the power in negative
now on differentiating
dy/dx = 0-2(-3)(2x-1)^-4 (2) -1
=12(2x-1)^-4-1
