1.

I don't know any rules for calculus, I will be learning the quotient, product and all that next year.

So I've managed to solve all this with finding derivatives by rule and the binomial expansion:)

(3x^2-1)^3= (3x^2)^3 (-1)^0 = 27x^6

= 3(3x^2)^2 (-1)^1 = 27x^4

= 3(3x^2)^1 (-1)^2 = 9x^2

= 1(3x^2)^0 (-1)^3 = -3x^2

dy

-- (27x^6+27x^4+9x^2-3x^2)

dx

= 162x^5-108x^3+18x
