6v^2-30v=0

解

6 v^{2} - 30 v = 0

v = 5, v = 0

解答ステップ

6 v^{2} - 30 v = 0

解くとthe二次式

v_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 6 \cdot 0}{2 \cdot 6}

(- 30)^{2} - 4 \cdot 6 \cdot 0 = 30

v_{1, 2} = \frac{- ( - 30 ) \pm 30}{2 \cdot 6}

解を分離する

v_{1} = \frac{- ( - 30 ) + 30}{2 \cdot 6}, v_{2} = \frac{- ( - 30 ) - 30}{2 \cdot 6}

v = \frac{- ( - 30 ) + 30}{2 \cdot 6} : 5

v = \frac{- ( - 30 ) - 30}{2 \cdot 6} : 0

二次equationの解:

v = 5, v = 0
