Hi all , again i got stuck onto this iffy bit , question is:

find dy/dx of the curve and hence its coordinates of the statinonary point.

y= 4 - 2/(2x-1)^2 -x

2. Relevant equations

du/dx x dy/du

3. The attempt at a solution

well this is how i started off:

let u = (2x-1) , y= 4-2(u)^-2 - x

du/dx= 2;dy/du:4u^-3-1

2x[4u^(-3)-1]

[8u^(-3) -2]

to find stationary points i will let dy/dx= 0 and solve the equation ?am i on the right track so far?
