3x^2-24x=0

解

3 x^{2} - 24 x = 0

x = 8, x = 0

解答ステップ

3 x^{2} - 24 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 \cdot 3 \cdot 0}{2 \cdot 3}

(- 24)^{2} - 4 \cdot 3 \cdot 0 = 24

x_{1, 2} = \frac{- ( - 24 ) \pm 24}{2 \cdot 3}

解を分離する

x_{1} = \frac{- ( - 24 ) + 24}{2 \cdot 3}, x_{2} = \frac{- ( - 24 ) - 24}{2 \cdot 3}

x = \frac{- ( - 24 ) + 24}{2 \cdot 3} : 8

x = \frac{- ( - 24 ) - 24}{2 \cdot 3} : 0

二次equationの解:

x = 8, x = 0
