24x^2-82x+48=0

解答

24 x^{2} - 82 x + 48 = 0

解答

x = \frac{8}{3}, x = \frac{3}{4}

+1

十进制

x = 2.66666 \dots, x = 0.75

求解步骤

24 x^{2} - 82 x + 48 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 82 ) \pm ( - 82 ) ^{2} - 4 \cdot 24 \cdot 48}{2 \cdot 24}

(- 82)^{2} - 4 \cdot 24 \cdot 48 = 46

x_{1, 2} = \frac{- ( - 82 ) \pm 46}{2 \cdot 24}

将解分隔开

x_{1} = \frac{- ( - 82 ) + 46}{2 \cdot 24}, x_{2} = \frac{- ( - 82 ) - 46}{2 \cdot 24}

x = \frac{- ( - 82 ) + 46}{2 \cdot 24} : \frac{8}{3}

x = \frac{- ( - 82 ) - 46}{2 \cdot 24} : \frac{3}{4}

二次方程组的解是:

x = \frac{8}{3}, x = \frac{3}{4}
