x^2-33x+125=0

解答

x^{2} - 33 x + 125 = 0

解答

x = \frac{33 + 589}{2}, x = \frac{33 - 589}{2}

+1

十进制

x = 28.63466 \dots, x = 4.36533 \dots

求解步骤

x^{2} - 33 x + 125 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 33 ) \pm ( - 33 ) ^{2} - 4 \cdot 1 \cdot 125}{2 \cdot 1}

(- 33)^{2} - 4 \cdot 1 \cdot 125 = 589

x_{1, 2} = \frac{- ( - 33 ) \pm 589}{2 \cdot 1}

将解分隔开

x_{1} = \frac{- ( - 33 ) + 589}{2 \cdot 1}, x_{2} = \frac{- ( - 33 ) - 589}{2 \cdot 1}

x = \frac{- ( - 33 ) + 589}{2 \cdot 1} : \frac{33 + 589}{2}

x = \frac{- ( - 33 ) - 589}{2 \cdot 1} : \frac{33 - 589}{2}

二次方程组的解是:

x = \frac{33 + 589}{2}, x = \frac{33 - 589}{2}
