Thread: Chain rule / quotient problem

So I use chain rule, which also involved use of the quotient rule.

5[(3x^2 + 2x + 1) / (3 - 2x^3 + x^2)]^4 * [(3 - 2x^3 + x^2) (6x+2) - (3x^2 + 2x + 1) (-6x^2 + 2x)] / (3-2x^3 + x^2)^2

Am I on the right track? It seems awfully long and I suspect I messed something up.

Everything's correct! Next time though try to use, in LaTeX, the "\frac" thing to write fractions: it'll be way clearer and easier to read.
