Question

Integrate: (-3x^2)/(x^3 +2)^2 without using log

Answer 1

substitute u = x^3

Answer 2

du = 3x^2 dx

Answer 3

substitude u=x^3+2 that will be more helpful

Answer 4

sorry substitute u = x^3+2

Answer 5

yes, thats what I meant i didnt type in the +2

Answer 6

\[\int\limits (-3x^2)dx/(x^3+2)^2=\int\limits -du/u^2=1/u+c=1/(x^3+2)+c\]

Answer 7

Thank you!

Answer 8
