y=[(x-5)(4x+3)]^5

I arrived at 5(6x-2)[(x-5)(4x+3)]^4

The answer is 5(8x-17)[(x-5)(4x+3)]^4

but I am not sure how they got the 8x-17

**Reiny**, Wednesday, February 23, 2011 at 10:43amfirst line derivative:

5((x-5)(4x+3))^4 (4(x-5) + (4x+3))

= 5((x-5)(4x+3))^4 (4x-20 + 4x+3)

= 5((x-5)(4x+3))^4 (8x - 17)
