Question

Calculate the derivative of the function
(3x-6/2x+6)^3

adamconner · Answer

u use the quotient rule and the chain rule

adamconner · Answer

3(3x-6/2x+6)[(2x+6*3)-(3x-6*2)/(2x+6)^2]

anonymous · Answer

is there another way to write it or something, my computer keeps saying it's the wrong answer

zepdrix · Answer

If you're trying to submit this onto a website, yes you'll need more brackets I'm afraid :(

3[(3x-6)/(2x+6)][((2x+6*3)-(3x-6*2))/((2x+6)^2)]

zepdrix · Answer

Oh there was a mistake in his quotient rule.. lemme fix that real quick.

3[(3x-6)/(2x+6)][((3(2x+6))-2(3x-6))/((2x+6)^2)]

Mmmm I think it will accept that, try it maybe :O
Lemme know if you have any questions about it.

zepdrix · Answer

Bahhh I keep screwing it up +_+
3[(3x-6)/(2x+6)]^2[((3(2x+6))-2(3x-6))/((2x+6)^2)]

It's very easy to miss stuff when you don't format the text all fancy :( grr
