簡約 (1/2x^2+1/3x-1)(3/4x^2-2/3x+1/9)

解

簡約

(\frac{1}{2} \cdot x^{2} + \frac{1}{3} \cdot x - 1) (\frac{3}{4} \cdot x^{2} - \frac{2}{3} \cdot x + \frac{1}{9})

(\frac{1}{2} x^{2} + \frac{1}{3} x - 1) (\frac{3 x ^{2}}{4} - \frac{2 x}{3} + \frac{1}{9})

解答ステップ

(\frac{1}{2} x^{2} + \frac{1}{3} x - 1) (\frac{3}{4} x^{2} - \frac{2}{3} x + \frac{1}{9})

\frac{3}{4} x^{2} = \frac{3 x ^{2}}{4}

\frac{2}{3} x = \frac{2 x}{3}

= (\frac{1}{2} x^{2} + \frac{1}{3} x - 1) (\frac{3 x ^{2}}{4} - \frac{2 x}{3} + \frac{1}{9})
