anonymous · Answer

take the derivative, replace x by 1

anonymous · Answer

my answer is 64 i got wrong... i just wanted to know the answer...

anonymous · Answer

$$x^2(x+2)^2=x^2(x^2+4x+4)=x^4+4x^3+4x$$
$$y'=4x^3+12x^2+4$$
i get 20

anonymous · Answer

the answer is in the letter i just forgot..and i need it

anonymous · Answer

oh i made a mistak

anonymous · Answer

$$x^2(x+2)^2=x^2(x^2+4x+4)=x^4+4x^3+4x^2$$
$$y'=4x^3+12x+8$$ now i get 24
