Question

integrate (x ^ 2)/(x ^ 2 + 1) dx​
please answer as soon as possible

Answer 1

Step-by-step explanation:

$given \: = > \frac{x ^{2} }{x ^{2} + 1 } dx \\ = \frac{ {x}^{2} \times dx}{ {x}^{2} + 1 } \\ = \frac{x ^{2}dx }{x + 1} \\ = \frac{x {}^{2} xd}{x + 1} \\ = \frac{x {}^{3}d }{x {}^{2} + 1 } ...$
