# Thread: How do you differentiate this?

1. ## How do you differentiate this?

√x(1-x)

I got an answer but I'm not sure if it is correct. I got -x(x-x^2)^-0.5

Thanks

Is it $\sqrt{x} (1 - x)$ or $\sqrt{x(1 - x)}$ ?

Also, it's easier to help if you post all your working, not just an answer.

3. Sorry its the second one, how do you write the equations like that?

Use the chain rule: differentiate Sqrt&#91;x&#40;1 - x&#41;&#93; - Wolfram|Alpha
