(3-u)(-2u(1+u^2)^-2)+(1+u^2)^(-1)(-1)=y'

Answer 4

(3-u) 1
------------- - -------------
-2u(1+u^2)^2 (1+u^2)

Answer 5

u=x^2-3
3-u=6-x^2
-2u=6-2x^2
1+u^2=x^4-6x+10

Answer 6

6-x^2 1
--------------------- - ---------------
(6-2x^2)(x^4-6x+1-)^2 x^4-6x+10

Answer 7

x=3t+3
6-x^2=-9t^2-18t-3
6x=18t+18
x^4=(3t+3)^4
