Question

evaluate the indefinite integral

Answer 1

\[\int\limits_{?}^{?}(x^3 +61)/(x^2 + 5x + 4)\]

Answer 2

make partial fractions first ... then it will be easy.

Answer 3

that's what i did, first I used long division to lower down the power of the numerator

Answer 4

\[\large Ax + \frac{Bx+C}{(x+1)(x+4)}\]

first change into this form.

Answer 5

i did it, and I ended up with \[\int\limits_{?}^{?}x-4 +\int\limits_{?}^{?} (17x - 77)/(x^2 + 5x +4) dx\]

Answer 6

can you integrate x-4??

Answer 7

(17x−77)/(x2+5x+4) ---change it into --> A/(x+4) + B/(x+1)

Answer 8

when I integrate eveything x^2/2 -4x + 20ln|x+1|- 3ln|x+4| + C
