Question

integration of x^4/x+1 ​

Answer 1

Step-by-step explanation:

Recall that

1

x

a

=

x

−

a

. We can then rewrite our integral as

∫

d

x

x

4

=

∫

x

−

4

d

x

Now, recall that

∫

x

a

d

x

where

a

≠

−

1

is equal to

x

a

+

1

a

+

1

+

C

where

C

is the constant of integration. Then,

∫

x

−

4

d

x

=

x

−

4

+

1

−

4

+

1

C

=

−
