Ok dz/dx x = 2y - 4y +y y = 4x + 3 dont think that is right!

hay everyone...need some help on the question :cry: I need to find dz/dx in terms of x and y, if: Z = x^2y - 2xy^2 + y - 8 and y = 2x^2 +3/x! tried solving it a few times, but its a difficult one! any help and working out would be great! :confused:
