## haterofmath 3 years ago g(x)= (x^2+x+1)(4-x)/ 2x-1 differentiate the given function

• This Question is Closed
1. Coolsector

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

2. haterofmath

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

3. Coolsector

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

4. KKJ

Differentiation using the quotient rule

5. KKJ

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