Question

how to integrate 12/(2x+1)*2 not by substitution.

Answer 1

first take the constant out \[\int\limits_{?}^{?}\frac{ 12 }{ (2x+1)^2 }dx=12\int\limits_{?}^{?}\frac{ 1 }{ (2x+1)^2 }dx\]

Answer 2

you there?

Answer 3

yeah thanks..:)

Answer 4

do you know how to continue?

Answer 5

yeah i do. :)

Answer 6

I got the result already if you want us to compare

Answer 7

it's -6/2x+1?

Answer 8

oh and +7

Answer 9

yep

Answer 10

thanks :)

Answer 11

-6/2x+1 i dont know about the +7

Answer 12

\[12 \int\limits_{}^{} (2x+1)^-2 dx = \frac{ 1 }{ 2 } \frac{ (2x+1}^-2{ -1 } = \frac{ -6 }{ 2x+1 }+c\]
