0.02844x^2-0.1596x+0.218=0

解答

0.02844 x^{2} - 0.1596 x + 0.218 = 0

解答

x = \frac{0.1596 + 0.00067248}{0.05688}, x = \frac{0.1596 - 0.00067248}{0.05688}

+1

十进制

x = 3.26181 \dots, x = 2.34999 \dots

求解步骤

0.02844 x^{2} - 0.1596 x + 0.218 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 0.1596 ) \pm ( - 0.1596 ) ^{2} - 4 \cdot 0.02844 \cdot 0.218}{2 \cdot 0.02844}

(- 0.1596)^{2} - 4 \cdot 0.02844 \cdot 0.218 = 0.00067248

x_{1, 2} = \frac{- ( - 0.1596 ) \pm 0.00067248}{2 \cdot 0.02844}

将解分隔开

x_{1} = \frac{- ( - 0.1596 ) + 0.00067248}{2 \cdot 0.02844}, x_{2} = \frac{- ( - 0.1596 ) - 0.00067248}{2 \cdot 0.02844}

x = \frac{- ( - 0.1596 ) + 0.00067248}{2 \cdot 0.02844} : \frac{0.1596 + 0.00067248}{0.05688}

x = \frac{- ( - 0.1596 ) - 0.00067248}{2 \cdot 0.02844} : \frac{0.1596 - 0.00067248}{0.05688}

二次方程组的解是:

x = \frac{0.1596 + 0.00067248}{0.05688}, x = \frac{0.1596 - 0.00067248}{0.05688}
