So my homework on this topic is due after the holidays and i am really struggling! Can anyone help?

1. Find (x squared -2)(x squared +2)/ x squared dx

2. calculate the shaded area enclosed between the parabolas with equations y= 1+10x-2x squared ans y= 1+5x-x squared. I ended up with 20.8.

3. calculate the shaded area enclosed between the curve y= (x+1)(x-1)(x-3) and the line y= 5x-5.

Hope this is legible.

Lehanne.
