x^2-26x+25=0

解答

x^{2} - 26 x + 25 = 0

解答

x = 25, x = 1

求解步骤

x^{2} - 26 x + 25 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 26 ) \pm ( - 26 ) ^{2} - 4 \cdot 1 \cdot 25}{2 \cdot 1}

(- 26)^{2} - 4 \cdot 1 \cdot 25 = 24

x_{1, 2} = \frac{- ( - 26 ) \pm 24}{2 \cdot 1}

将解分隔开

x_{1} = \frac{- ( - 26 ) + 24}{2 \cdot 1}, x_{2} = \frac{- ( - 26 ) - 24}{2 \cdot 1}

x = \frac{- ( - 26 ) + 24}{2 \cdot 1} : 25

x = \frac{- ( - 26 ) - 24}{2 \cdot 1} : 1

二次方程组的解是:

x = 25, x = 1
