Cho tam giác $A B C$ có $G$ là trọng tâm.

a) Hāy phân tích véctơ $\overrightarrow{A G}$ theo hai vectơ $\overrightarrow{A B}, \overrightarrow{A C}$.

b) Gọi $E, F$ là hai điểm xác định bởi các điều kiện: $\overrightarrow{E A}=2 \overrightarrow{E B}, 3 \overrightarrow{F A}+2 \overrightarrow{F C}=\overrightarrow{0}$. Hāy phân tích $\overrightarrow{E F}$ theo hai vecto $\overrightarrow{A B}, \overrightarrow{A C}$.
