[atar90plus]

I was wondering if you guys could help me with the homework questions i could not do. Could you guys please show all the working out and solutions.

7. (1-x)^3 (3+x)^2
8. (7+x)^2 (3-2x)^2
13. (3x+5) root1-x^2
14. (1-4x) (root7x-2x^2)

5. x^2+1 / x^2-x-1
6. x^2+x+1 / x^2-x-1

Thanks

7.(1-x)^3 (3+x)^2

use product + chain rule.
uv' + vu' , (1-x)^3 (3+x)^2
= [(1-x)^3 * 2(3+x)] + [(3+x)^2 * -3(1-x)^2]


where de heck do u get these questions from?
