evaluate this derivative

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

your answer is a 100% correct they pulled out a negative one and hence why you have opposite signs great substitution

OpenStudy (anonymous):

yeah right

OpenStudy (anonymous):

oh, thanks

OpenStudy (anonymous):

i was like man how could it be wrong

OpenStudy (anonymous):

nope good job, if you have anymore i love integrals

OpenStudy (anonymous):

nope good job, if you have anymore i love integrals

OpenStudy (anonymous):

but if they pulled out a negative 1, how come, it should be like this -1( .......)

OpenStudy (anonymous):

?

OpenStudy (anonymous):

i guess not
