first do the long divison and then use partial fraction method to integrate
gerald

hey
anonymous
  • anonymous
so that length question i think i solved it
anonymous
  • anonymous
ok
anonymous
  • anonymous
so working on this question i know you can find common terms in this question i am just trying to find that
anonymous
  • anonymous
i mean i am refering to gerald's question
anonymous
  • anonymous
lets do long division
anonymous
  • anonymous
hmm okay, but i was thinking if we just rearrange and ge trid of the common terms

did it work
anonymous

you get integral x^3 - x^2
anonymous
  • anonymous
so basically gotta integrate x^3 -x^2
anonymous
  • anonymous
and that will give you ((x^4)/4)-(x^3/3) + C
anonymous
  • anonymous
yes

u just want to find the first derivative right?
anonymous
  • anonymous
are we talking about derivatives or integrals? because you just integrated
anonymous
  • anonymous
uhm cantorset...do you know what you are talking about?
anonymous
  • anonymous
according to the questions, it says "derivatives" , right?
anonymous
  • anonymous
you can use the quotient rule to solve this if you like
anonymous
  • anonymous
do ther derivative with quotient rule. ((x+2)(4x^3+3x^2-2x^2)-(x^4+x+3-2x^2))/(x+2)^2
anonymous
  • anonymous
that is the correct approach, ignore whatever cantorset mentioned its nonsense
anonymous
  • anonymous
d/dx of f(x)/g(x)=( f'(x)g(x)-f(x)g'(x))/(g(x))^2
anonymous
  • anonymous
okay, so when u want to find the derivative, here , its better if u use the 'u/v' rule.. which is \[(v u \prime-u v \prime )/v ^{2}\]
anonymous
  • anonymous
wher u =numerator & v=denominator
anonymous
  • anonymous
exactly, thats correct @avalanche :)
anonymous
  • anonymous
great minds think alike :)
anonymous
  • anonymous
yupp :):)
