-3x^2-4x+12=0

解

- 3 x^{2} - 4 x + 12 = 0

解

x = - \frac{2 ( 1 + 10 )}{3}, x = \frac{2 ( 10 - 1 )}{3}

+1

十進法表記

x = - 2.77485 \dots, x = 1.44151 \dots

解答ステップ

- 3 x^{2} - 4 x + 12 = 0

解くとthe二次式

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

(- 4)^{2} - 4 (- 3) \cdot 12 = 410

x_{1, 2} = \frac{- ( - 4 ) \pm 4 10}{2 ( - 3 )}

解を分離する

x_{1} = \frac{- ( - 4 ) + 4 10}{2 ( - 3 )}, x_{2} = \frac{- ( - 4 ) - 4 10}{2 ( - 3 )}

x = \frac{- ( - 4 ) + 4 10}{2 ( - 3 )} : - \frac{2 ( 1 + 10 )}{3}

x = \frac{- ( - 4 ) - 4 10}{2 ( - 3 )} : \frac{2 ( 10 - 1 )}{3}

二次equationの解:

x = - \frac{2 ( 1 + 10 )}{3}, x = \frac{2 ( 10 - 1 )}{3}

x^{2} - 5.1 x + 6.3 = 0

(x^2)/3 =4x-x^2

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

(x - 2) (x - 6) = 5
