I got a different answer from the BOB I couldn't find out what I have done wrong
I got dy/dx​=8(x+1)(2x+5)3+(2x+5)4.
My working out:
u'=1 v'=4(2x+5)^5
dy/dx=1(2x+5)^4+(4(2x+5)^3)(x+1)
=(2x+5)^3+(4(2x+5)^3)
(x+1)*2
=(2x+5)^3+8(2x+5)^3)(x+1)

y'=(2x+5)^3+8(2x+5)^3)(x+1)
=(2x+5)3*(2x+5)+8(2x+5)3^(x+1)
=(2x+5)3*(2x+5+8x+8)
=(2x+5)3*(10x+13)​
BOB (2x+5)^3(10x+13)
