-3x^2-50x-243=4x

解

- 3 x^{2} - 50 x - 243 = 4 x

x = - 9

解答ステップ

- 3 x^{2} - 50 x - 243 = 4 x

4 x

- 3 x^{2} - 54 x - 243 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 54 ) \pm ( - 54 ) ^{2} - 4 ( - 3 ) ( - 243 )}{2 ( - 3 )}

(- 54)^{2} - 4 (- 3) (- 243) = 0

x_{1, 2} = \frac{- ( - 54 ) \pm 0}{2 ( - 3 )}

x = \frac{- ( - 54 )}{2 ( - 3 )}

\frac{- ( - 54 )}{2 ( - 3 )} = - 9

x = - 9

二次equationの解:

x = - 9
