z^2-50z=0

解

z^{2} - 50 z = 0

z = 50, z = 0

解答ステップ

z^{2} - 50 z = 0

解くとthe二次式

z_{1, 2} = \frac{- ( - 50 ) \pm ( - 50 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 50)^{2} - 4 \cdot 1 \cdot 0 = 50

z_{1, 2} = \frac{- ( - 50 ) \pm 50}{2 \cdot 1}

解を分離する

z_{1} = \frac{- ( - 50 ) + 50}{2 \cdot 1}, z_{2} = \frac{- ( - 50 ) - 50}{2 \cdot 1}

z = \frac{- ( - 50 ) + 50}{2 \cdot 1} : 50

z = \frac{- ( - 50 ) - 50}{2 \cdot 1} : 0

二次equationの解:

z = 50, z = 0
