2. anonymous

we can solve it by |dw:1358846643095:dw|

3. anonymous

int of u * v + int( int v * u) +c

4. anonymous

i think by this u can get the ans

5. anonymous

if you do u substitution would it be the same answer?

$\int\limits 5 \sqrt(2-7 x) x dx = -2/147 (2-7 x)^(3/2) (21 x+4)+constant$

7. anonymous

substitution and integration by parts will differ by a constant.

@rishabh.mission the radical expression is $\sqrt{2-7x}$ not $\sqrt{2-7x\color{red}{^2}}$

9. rishabh.mission

Complete solution

lol

11. rishabh.mission

lol y?
