化简-y^2(y-x^4-(y^4)/4)

解答

化简

- y^{2} (y - x^{4} - \frac{y ^{4}}{4})

- y^{2} (y + \frac{- 4 x ^{4} - y ^{4}}{4})

求解步骤

- y^{2} (y - x^{4} - \frac{y ^{4}}{4})

合并

y - x^{4} - \frac{y ^{4}}{4} : y + \frac{- x ^{4} \cdot 4 - y ^{4}}{4}

= - y^{2} (y + \frac{- x ^{4} \cdot 4 - y ^{4}}{4})

= - y^{2} (y + \frac{- 4 x ^{4} - y ^{4}}{4})
