3x^2+2sqrt(6)x+2=0

解

3 x^{2} + 26 x + 2 = 0

x = - \frac{2}{3}

十進法表記

x = - 0.81649 \dots

解答ステップ

3 x^{2} + 26 x + 2 = 0

解くとthe二次式

x_{1, 2} = \frac{- 2 6 \pm ( 2 6 ) ^{2} - 4 \cdot 3 \cdot 2}{2 \cdot 3}

(26)^{2} - 4 \cdot 3 \cdot 2 = 0

x_{1, 2} = \frac{- 2 6 \pm 0}{2 \cdot 3}

x = \frac{- 2 6}{2 \cdot 3}

\frac{- 2 6}{2 \cdot 3} = - \frac{2}{3}

x = - \frac{2}{3}

二次equationの解:

x = - \frac{2}{3}
