Question

derivative of (2x-x^2)/(x^2-2x+1)

Answer 1

The answer is suppose to be -2/(x-1)^3 but I can't get that answer.

Answer 2

Have you factored it out?

Answer 3

First factor it out.

Answer 4

It isn't necessary, but it could make the problem a whole lot easier.

Answer 5

so: x(2-x)/ (x-1)^2 ?

Answer 6

Yeah that looks about right. Have you tried the quotient rule?

Answer 7

It seems factoring won't help this time because they don't have common roots.

Answer 8

do u want me to upload a photo of my work on paper, so maybe u can sot what i did wrong?

Answer 9

Did you try factoring out the numerator and denominator to see if it lead you to your answer?
