## anonymous 4 years ago g(x)= (x^2+x+1)(4-x)/ 2x-1 differentiate the given function

1. anonymous

f(u,v) = u/v f' = (u'v-v'u)/(v^2) does this help ?

2. anonymous

no not really....i understand what you put up, but there's like two part to the numerator

3. anonymous

so you can either use the product rule or just simplify the numerator then differentiate

4. anonymous

Differentiation using the quotient rule

$y = \frac{ u }{ v } \rightarrow \frac{ dy }{ dx } = \frac{ v \frac{ du }{ dx }-u \frac{ dv }{dx } }{ v^2 }$
