Bài 3. Rút gọn biểu thức:
a/ \( x^2 \left( \frac{1}{x^{\frac{2}{3}}} - \frac{2}{3} x \right) \left( -x^2 - \frac{1}{2} x + \frac{5}{3} x^3 \right) \)
b/ \( \left( 2x - 1 \right) \cdot \left( 2 + 3x \right) - 0.5x(x - 2, 4) - \frac{11}{2} x^2 + 2 \)
c/ \( \left( x + 3 \right) \left( \frac{4}{3} x^2 + 12x - \frac{14}{9} \right) + 3x + 9 \left( -\frac{4}{9} x^2 - 2x + \frac{5}{27} \right) \)
d/ \( \left( x + 5 \right) \cdot \left( x - 1 \right) \cdot \left( x - \frac{1}{3} - x^2 - 25 \right) \)
