因数 1-1/8 p^3

解

因数

1 - \frac{1}{8} p^{3}

- (\frac{p}{2} - 1) (\frac{p ^{2}}{4} + \frac{p}{2} + 1)

解答ステップ

1 - \frac{1}{8} p^{3}

因数

1 - \frac{p ^{3}}{8} : - (\frac{p}{2} - 1) ((\frac{1}{2})^{2} p^{2} + \frac{1}{2} p + 1)

= - (\frac{p}{2} - 1) ((\frac{1}{2})^{2} p^{2} + \frac{1}{2} p + 1)

簡素化

- (\frac{p}{2} - 1) ((\frac{1}{2})^{2} p^{2} + \frac{1}{2} p + 1) : - (\frac{p}{2} - 1) (\frac{p ^{2}}{4} + \frac{p}{2} + 1)

= - (\frac{p}{2} - 1) (\frac{p ^{2}}{4} + \frac{p}{2} + 1)
