## ksaimouli one year ago integrate

1. ksaimouli

$\int\limits_{}^{}\frac{ x^2+3 }{ x-1}dx$

2. TuringTest

use polynomial long division

3. ksaimouli

i got |dw:1356474256088:dw|

4. ksaimouli

@TuringTest

5. TuringTest

yes, so what is your new integrand?

6. ksaimouli

how to write? no idea

7. TuringTest

yeah, you didn't show you work too clearly|dw:1356474423392:dw|so you got x+1 with remainder 4

8. ksaimouli

|dw:1356474525330:dw|

9. TuringTest

that's right, now integrate

10. ksaimouli

from here i can catch up last question when to

11. ksaimouli

use long division

12. ksaimouli

i mean by just seeing the question how do u know to do long division

When you need to integrate a rational expression, and the polynomial in the numerator has a higher degree than the polynomial in the denominator, use polynomial long division.
