Question

Integrate ((x+2)^2) / x dx

Answer 1

\[\int \frac{(x+2)^2}{x}dx\]

Answer 2

maybe u-sub

Answer 3

Expand (x+2)^2
(a+b)^2 = a^2+2ab+b^2

Answer 4

yeah; and break it into fractions, easier!

Answer 5

@ieatpi can u ?

Answer 6

I don't think we've learned that yet

Answer 7

what have you learnt

Answer 8

u haven't learnt (a+b)^2 ??

Answer 9

you're too advanced @hartnn

Answer 10

well for those who started calculus , (a+b)^2 isn't advanced.

Answer 11

ok so \[\int\limits_{}^{}(x^{2}+4x + 4)/ x\], now what?

Answer 12

you don't know online schools then @hartnn

Answer 13

lol an advanced method is to use u-sub and long division; for this question igba :P

Answer 14

then break it into fractions!

Answer 15

\[\int\limits\frac{x^{2}+4x+4}{x} => \int\limits\frac{x^{2}}{x} +\frac{4x}{x} +\frac{4}{x} \]

Answer 16

omg, I'm an idiot

Answer 17

lol thanks guys
