144.3x^2-350.98x+49.9947=0

解答

144.3 x^{2} - 350.98 x + 49.9947 = 0

解答

x = \frac{350.98 + 94330.01956}{288.6}, x = \frac{350.98 - 94330.01956}{288.6}

+1

十进制

x = 2.28036 \dots, x = 0.15193 \dots

求解步骤

144.3 x^{2} - 350.98 x + 49.9947 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 350.98 ) \pm ( - 350.98 ) ^{2} - 4 \cdot 144.3 \cdot 49.9947}{2 \cdot 144.3}

(- 350.98)^{2} - 4 \cdot 144.3 \cdot 49.9947 = 94330.01956

x_{1, 2} = \frac{- ( - 350.98 ) \pm 94330.01956}{2 \cdot 144.3}

将解分隔开

x_{1} = \frac{- ( - 350.98 ) + 94330.01956}{2 \cdot 144.3}, x_{2} = \frac{- ( - 350.98 ) - 94330.01956}{2 \cdot 144.3}

x = \frac{- ( - 350.98 ) + 94330.01956}{2 \cdot 144.3} : \frac{350.98 + 94330.01956}{288.6}

x = \frac{- ( - 350.98 ) - 94330.01956}{2 \cdot 144.3} : \frac{350.98 - 94330.01956}{288.6}

二次方程组的解是:

x = \frac{350.98 + 94330.01956}{288.6}, x = \frac{350.98 - 94330.01956}{288.6}
