Cho hàm số f(x) = (x^3-x+3) (x+2)^2Mệnh đề nào đúng?

A. $5f\text{'}\left(-1\right)-\frac{1}{2}f\text{'}\left(-2\right)=302$ 

B. $f\text{'}\left(2\right)-5f\text{'}\left(-2\right)=32$

C. $\frac{5f\text{'}\left(2\right)+f\text{'}\left(-1\right)}{3}=12$ 

D. $3f\text{'}\left(2\right)-\frac{1}{4}f\text{'}\left(-1\right)=742$
