how did u get the bracket behind the (4x+1)^3
Hi! Make use of chain rule of differentiation by finding the derivative of what is within the bracket ie (4x+1) to get 4.
how about the 32-48x
Factories out (4x+1)^3, so what remains will be 16(2-3x)= 32-48x
then the -12x plus 3?
Same ! Factorise out (4x+1)^3 so what remains is -3(4x+1) which is -12x-3
Just to simplify the whole expression

i don’t understand the part d
Make use of product rule! It’s similar to part c.
