I worked this problem out but I do not see my answer as a choice. How would you work this problem out.

Can you show me step by step way so I can look at how I did the problem wrong.

Find the derivative of the following function.

y= 3x^2 +25x^-2 - 14x / 4x^8 + 14

This is Business Analysis 2372 homework.

Once you help me I will figure where I went wrong. Thanks
