500S^2+60S+1=0

解答

500 S^{2} + 60 S + 1 = 0

解答

S = - \frac{1}{50}, S = - \frac{1}{10}

+1

十进制

S = - 0.02, S = - 0.1

求解步骤

500 S^{2} + 60 S + 1 = 0

使用求根公式求解

S_{1, 2} = \frac{- 60 \pm 6 0 ^{2} - 4 \cdot 500 \cdot 1}{2 \cdot 500}

6 0^{2} - 4 \cdot 500 \cdot 1 = 40

S_{1, 2} = \frac{- 60 \pm 40}{2 \cdot 500}

将解分隔开

S_{1} = \frac{- 60 + 40}{2 \cdot 500}, S_{2} = \frac{- 60 - 40}{2 \cdot 500}

S = \frac{- 60 + 40}{2 \cdot 500} : - \frac{1}{50}

S = \frac{- 60 - 40}{2 \cdot 500} : - \frac{1}{10}

二次方程组的解是:

S = - \frac{1}{50}, S = - \frac{1}{10}
