There is one place of uncertainty in your question: in the exponent you have written 15+4x2-2. I am going to assume that you mean 13+4x2. Iff you meant something different, you will need to modify the answer accordingly.
y'(x) = 3(13+4x2)(8x)(x3-7x+2)(3x2-7)

it supposed to be (x^3-7x+2)^15 +4x^2-212/05/18
