Expert Solution
Step 1

The given definite integral can be evaluated using the method of substitution by making the following substitution:

u=x-3      dudx=12x-3·(1-0)      du=dx2x-3

 

Also, we will have:

u2=x-3      x=u2+3      x+6=u2+9

 

Further, the limits will change as shown below:

 

At, x=6  we get u=6-3=3      and       At, x=12  we get u=12-3=9=3

steps
