Solution

We have the following expression:

We can use the product rule and we have the following:

$y^(\prime)=2(2x+5)\cdot2\cdot(x-4)+(2x+5)^2\cdot(1)$

Then we can simplify and we have:

$y^(\prime)=(8x+20)(x-4)+(2x+5)^2=8x^2-32x+20x-80+4x^2+20x+25$

If we simplify we got:

$y^(\prime)=12x^2+8x-55$
