-3x^2+14x-12=0

解

- 3 x^{2} + 14 x - 12 = 0

解

x = \frac{7 - 13}{3}, x = \frac{7 + 13}{3}

+1

十進法表記

x = 1.13148 \dots, x = 3.53518 \dots

解答ステップ

- 3 x^{2} + 14 x - 12 = 0

解くとthe二次式

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 ( - 3 ) ( - 12 )}{2 ( - 3 )}

1 4^{2} - 4 (- 3) (- 12) = 213

x_{1, 2} = \frac{- 14 \pm 2 13}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- 14 + 2 13}{2 ( - 3 )}, x_{2} = \frac{- 14 - 2 13}{2 ( - 3 )}

x = \frac{- 14 + 2 13}{2 ( - 3 )} : \frac{7 - 13}{3}

x = \frac{- 14 - 2 13}{2 ( - 3 )} : \frac{7 + 13}{3}

二次equationの解:

x = \frac{7 - 13}{3}, x = \frac{7 + 13}{3}
