Not quite. There's a wrong sign at the end, and the differential of the cubic root is not right either. Perhaps you should write it to ease the differentiation.
better?
Still a problem with the root: the derivative of is , hence... O wait, it just changed. There's still a problem: there is a + in front of the root.
