s^2-s=0

解

s^{2} - s = 0

s = 1, s = 0

解答ステップ

s^{2} - s = 0

解くとthe二次式

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

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

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

解を分離する

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

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

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

二次equationの解:

s = 1, s = 0
