-12x^2+11x-2=0

解

- 12 x^{2} + 11 x - 2 = 0

解

x = \frac{1}{4}, x = \frac{2}{3}

+1

十進法表記

x = 0.25, x = 0.66666 \dots

解答ステップ

- 12 x^{2} + 11 x - 2 = 0

解くとthe二次式

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 ( - 12 ) ( - 2 )}{2 ( - 12 )}

1 1^{2} - 4 (- 12) (- 2) = 5

x_{1, 2} = \frac{- 11 \pm 5}{2 ( - 12 )}

解を分離する

x_{1} = \frac{- 11 + 5}{2 ( - 12 )}, x_{2} = \frac{- 11 - 5}{2 ( - 12 )}

x = \frac{- 11 + 5}{2 ( - 12 )} : \frac{1}{4}

x = \frac{- 11 - 5}{2 ( - 12 )} : \frac{2}{3}

二次equationの解:

x = \frac{1}{4}, x = \frac{2}{3}
