Find the derivative of y= ( 15x5 +6x4 +17) ( -7x7- 179x)

I am stuck between two choices I think are right. How would you work through the problem.

This is Business Analysis 2372

This is the one I think is correct

(75x4 + 24x3 ) ( -7x7 -179x) + ( 15x5 +6x4 +17) ( -49x6 -179)

If this is not correct can you explain what the correct solution is. Thanks
