anonymous · Answer

I think you need to find the antiderivative.

anonymous · Answer

i tried 
 i used division 
but i couldn`t simplify the denominator

anonymous · Answer

Subtract the power by 1 and the denominator by one also.

anonymous · Answer

x^4. = x^4-1
            4-1

anonymous · Answer

So you get 1/3x^3

anonymous · Answer

9(1/3)= 3
So you get for the first one 3x^3
Hmmmmmm that doesn't seen to be working.

anonymous · Answer

Do you have the answer? Is the first one 9/5x^5?

anonymous · Answer

If it is instead of subtracting 1 you need to add 1 to what I did above.

anonymous · Answer

impartial fractions maybe

anonymous · Answer

partial fractions my bad

anonymous · Answer

X^(n+1)/n+1

anonymous · Answer

i don`t have the answer 
yeah >>>partial fractions 
i`ii try the(n+1) method  thanx

anonymous · Answer

use long division to break down the fraction cause num.power has to be smaller than denom,

anonymous · Answer

i did the division 
 couldn`t simplify the denominator

anonymous · Answer

9/5x^5+48/4x^4+37/3x^3-20/2x^2+3x
