d_{1}-3x^2+4x=0

解

d_{1} - 3 x^{2} + 4 x = 0

解

x = - \frac{- 2 + 3 d _{1} + 4}{3}, x = \frac{3 d _{1} + 4 + 2}{3}

解答ステップ

d_{1} - 3 x^{2} + 4 x = 0

標準的な形式で書く

a x^{2} + b x + c = 0

- 3 x^{2} + 4 x + d_{1} = 0

解くとthe二次式

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

簡素化

4^{2} - 4 (- 3) d_{1} : 2 4 + 3 d_{1}

x_{1, 2} = \frac{- 4 \pm 2 4 + 3 d _{1}}{2 ( - 3 )}

解を分離する

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

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

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

二次equationの解:

x = - \frac{- 2 + 3 d _{1} + 4}{3}, x = \frac{3 d _{1} + 4 + 2}{3}
