-96.52131+3.06658x-0.02412x^2=0

解答

- 96.52131 + 3.06658 \cdot x - 0.02412 \cdot x^{2} = 0

解答

x = \frac{3.06658 - 0.0915369076}{0.04824}, x = \frac{3.06658 + 0.0915369076}{0.04824}

+1

十进制

x = 57.29745 \dots, x = 69.84101 \dots

求解步骤

- 96.52131 + 3.06658 x - 0.02412 x^{2} = 0

改写成标准形式

a x^{2} + b x + c = 0

- 0.02412 x^{2} + 3.06658 x - 96.52131 = 0

使用求根公式求解

x_{1, 2} = \frac{- 3.06658 \pm 3.0665 8 ^{2} - 4 ( - 0.02412 ) ( - 96.52131 )}{2 ( - 0.02412 )}

3.0665 8^{2} - 4 (- 0.02412) (- 96.52131) = 0.0915369076

x_{1, 2} = \frac{- 3.06658 \pm 0.0915369076}{2 ( - 0.02412 )}

将解分隔开

x_{1} = \frac{- 3.06658 + 0.0915369076}{2 ( - 0.02412 )}, x_{2} = \frac{- 3.06658 - 0.0915369076}{2 ( - 0.02412 )}

x = \frac{- 3.06658 + 0.0915369076}{2 ( - 0.02412 )} : \frac{3.06658 - 0.0915369076}{0.04824}

x = \frac{- 3.06658 - 0.0915369076}{2 ( - 0.02412 )} : \frac{3.06658 + 0.0915369076}{0.04824}

二次方程组的解是:

x = \frac{3.06658 - 0.0915369076}{0.04824}, x = \frac{3.06658 + 0.0915369076}{0.04824}
