6x^2+6x-2=0

解

6 x^{2} + 6 x - 2 = 0

解

x = \frac{- 3 + 21}{6}, x = - \frac{3 + 21}{6}

+1

十進法表記

x = 0.26376 \dots, x = - 1.26376 \dots

解答ステップ

6 x^{2} + 6 x - 2 = 0

解くとthe二次式

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

6^{2} - 4 \cdot 6 (- 2) = 221

x_{1, 2} = \frac{- 6 \pm 2 21}{2 \cdot 6}

解を分離する

x_{1} = \frac{- 6 + 2 21}{2 \cdot 6}, x_{2} = \frac{- 6 - 2 21}{2 \cdot 6}

x = \frac{- 6 + 2 21}{2 \cdot 6} : \frac{- 3 + 21}{6}

x = \frac{- 6 - 2 21}{2 \cdot 6} : - \frac{3 + 21}{6}

二次equationの解:

x = \frac{- 3 + 21}{6}, x = - \frac{3 + 21}{6}
