Cho hàm số f(x)=(x^3-x+3)(x+2)^2. Mệnh đề nào đúng? f'(2)-5f'(-2)=32

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

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

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

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