$\int\limits_{?}^{?}(ax+b)/(\sqrt{ax ^{2}+2bx+c} dx$

2. anonymous

i have no idea what to do so a workout would be extremely helpful

3. anonymous

the dx is suppose to be separate

4. precal

use the u du method $u=ax^2+2bx+cd$ $du=2ax+2d dx$ you only have ax+b dx but you could multiply a 2 2(ax+b) dx just remember to multiply by 1/2 in front

5. precal

|dw:1328472937915:dw|

6. precal

you need to add 1/2 and 2

Now you can finish the problem
