3 (a - \frac{1}{6})^{2} - \frac{145}{12}

展开

3 (a - \frac{1}{6})^{2} : 3 \cdot \frac{36 a ^{2} - 12 a + 1}{36}

= 3 \cdot \frac{36 a ^{2} - 12 a + 1}{36} - \frac{145}{12}

化简

3 \cdot \frac{36 a ^{2} - 12 a + 1}{36} : \frac{36 a ^{2} - 12 a + 1}{12}

= \frac{36 a ^{2} - 12 a + 1}{12} - \frac{145}{12}
