Please help. What is the area of the region which is bounded by the x-axis and by the graph of y=(20(7-x)(x-3))/x^2. Thank you for any help.

integrate from x=3 to 7

multipy it out, then you should have several integrals...

(7-x)(x-3)
7x+3x-x^2-21

int(10x/x^2 dx -x^2/x^2 dx -21/x^2dx)

10lnx -x +21/x all over limits, then multipy by 20

check that
