簡約 (-3/2)^2-9-((-3/2)^2+3(-3/2))

解

簡約

(- \frac{3}{2})^{2} - 9 - ((- \frac{3}{2})^{2} + 3 (- \frac{3}{2}))

- \frac{9}{2}

十進法表記

- 4.5

解答ステップ

(- \frac{3}{2})^{2} - 9 - ((- \frac{3}{2})^{2} + 3 (- \frac{3}{2}))

(- \frac{3}{2})^{2} = \frac{9}{4}

- ((- \frac{3}{2})^{2} + 3 (- \frac{3}{2})) = \frac{9}{4}

= \frac{9}{4} - 9 + \frac{9}{4}

\frac{9}{4} - 9 + \frac{9}{4} = - \frac{9}{2}

= - \frac{9}{2}
