## Homework Statement

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

Find y` and y``

## Homework Equations

y= [tex]\sqrt[3]{x^2+x+1}[/tex]

## The Attempt at a Solution

for the 1st problem i get to

y`=(-4x^2+7x-4)/(x^2-x+1)^2 by u/v method but i have to make it as

-3(x^2-3x+1)/(x^2-x+1)^3

for the second problem

i get to y`= (2x+1)/(3(x^2+x+1)^2/3)

then i m messing it up to convert them in a factored forum to solve for x as i have to sketch graphs of them. There are so many problems like this & each time i m feeling dfficulties while making them in a factored form.IS there any intelligent stretegy to do this sort of problems more easily? I will be very glad to know that.

Thanks :)
