Question

\[Evaluate \int\limits [(2x+1)(x ^{2}+x+9)]\]

Answer 1

well just expand it..and integrate it one by one :)

Answer 2

i know how to solve easy integrals :P

Answer 3

Lol, here's a nice one to think about @angela210793
\[ \int \frac{1}{ln(x-1)}\]

Answer 4

@Omniscience there's an easier way. let u = x^2 + x + 9

du = 2x + 1

therefore the integral becomes
\[\int udu\]

Answer 5

keep in mind if the asker knows u-sub first :)

Answer 6

i said easyyyy :P
:(

Answer 7

who doesnt heh

Answer 8

:)

Answer 9

well if he/she does he wont be asking these type of questions :)

Answer 10

and im pretty sure @Beatles knows u-sub

Answer 11

he even knows integration by parts, trig sub and partial fractions

Answer 12

that's why i proposed u-sub ;)

Answer 13

well i didnt know that. if he knows that much why would he ask this question? :)

Answer 14

WATEVER.

Answer 15
