g(x)= (x^2+x+1)(4-x)/ 2x-1 differentiate the given function
f(u,v) = u/v f' = (u'v-v'u)/(v^2) does this help ?
no not really....i understand what you put up, but there's like two part to the numerator
so you can either use the product rule or just simplify the numerator then differentiate
Differentiation using the quotient rule
\[y = \frac{ u }{ v } \rightarrow \frac{ dy }{ dx } = \frac{ v \frac{ du }{ dx }-u \frac{ dv }{dx } }{ v^2 }\]
