解答ステップ

\int_{0}^{3} x^{3} - 4 x^{2} + 4 x d x

総和規則を適用する:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{3} x^{3} d x - \int_{0}^{3} 4 x^{2} d x + \int_{0}^{3} 4 x d x

\int_{0}^{3} x^{3} d x = \frac{81}{4}

\int_{0}^{3} 4 x^{2} d x = 36

\int_{0}^{3} 4 x d x = 18

= \frac{81}{4} - 36 + 18

簡素化

\frac{81}{4} - 36 + 18 : \frac{9}{4}

= \frac{9}{4}
