c^2-10c=0

解

c^{2} - 10 c = 0

c = 10, c = 0

解答ステップ

c^{2} - 10 c = 0

解くとthe二次式

c_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot 0 = 10

c_{1, 2} = \frac{- ( - 10 ) \pm 10}{2 \cdot 1}

解を分離する

c_{1} = \frac{- ( - 10 ) + 10}{2 \cdot 1}, c_{2} = \frac{- ( - 10 ) - 10}{2 \cdot 1}

c = \frac{- ( - 10 ) + 10}{2 \cdot 1} : 10

c = \frac{- ( - 10 ) - 10}{2 \cdot 1} : 0

二次equationの解:

c = 10, c = 0
