Question

Substitution Rule (integrals).
See below.

Answer 1

\[\int\limits \frac{ x^2+3x+7 }{ \sqrt{x} }\]

Answer 2

my work so far:
u = x
du = dx
\[\int\limits \frac{ u^2+3u+7 }{ u^{1/2} }du\]
since u = x
but my question is, how do you do the top part?

Answer 3

use direct division... simplify it

Answer 4

then integrate it

Answer 5

ohhh, that makes so much more sense! thank you :D

Answer 6
