s^2-s=0

解答

s^{2} - s = 0

解答

s = 1, s = 0

求解步骤

s^{2} - s = 0

使用求根公式求解

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}

将解分隔开

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

二次方程组的解是:

s = 1, s = 0

16.7-(20x^2)/(10)=0

16.7 - \frac{20 x ^{2}}{10} = 0

- x^{2} + 10 x + 25 = 0

10 = 3 Q^{2} - 18 Q + 5
