Question

evaluate this derivative

Answer 1

I mean integral:


\[\int\limits_{}^{}(x+1)^2(1-x)^5\]

Answer 2

so i let u=1-x and then also rewrote x as being 1-u

Answer 3

i integrated and got the a similar answer as my book, but my signs were off

Answer 4

i got : 2/3(1-x)^6 - 4/7(1-x)^7 + 1/8(1-x)^8 +c

Answer 5

but my answer was suppose to be -1/8(1-x)^8 + 4/7(1-x)^7 - 2/3(1-x)^6 +c

Answer 6

your answer is a 100% correct

they pulled out a negative one and hence why you have opposite signs
great substitution

Answer 7

yeah right

Answer 8
