Derivatives with Quotient Law Help!
I have a test tomorow, any help is much appreciated! :)
Dervive using the quotient rule:
[(2-x)^3] / [(x+1)^2]
My attempt:
= [(x+1)^2 (3(2-x)^2)]-[(2-x)^3 2(x+1)]
When I try expanding I get the wrong answer. The final answer's:
[(2-x)^2 (-x-7)] / (x+1)^3
Thankyou in advance!
