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

    you get integral x^3 - x^2

  26. anonymous

    so basically gotta integrate x^3 -x^2

    and that will give you ((x^4)/4)-(x^3/3) + C

    u just want to find the first derivative right?

    are we talking about derivatives or integrals? because you just integrated

    according to the questions, it says "derivatives" , right?

    you can use the quotient rule to solve this if you like

    do ther derivative with quotient rule. ((x+2)(4x^3+3x^2-2x^2)-(x^4+x+3-2x^2))/(x+2)^2

    that is the correct approach, ignore whatever cantorset mentioned its nonsense

    d/dx of f(x)/g(x)=( f'(x)g(x)-f(x)g'(x))/(g(x))^2

    okay, so when u want to find the derivative, here , its better if u use the 'u/v' rule.. which is \[(v u \prime-u v \prime )/v ^{2}\]
