m^2-12m=0

解答

m^{2} - 12 m = 0

解答

m = 12, m = 0

求解步骤

m^{2} - 12 m = 0

使用求根公式求解

m_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 12)^{2} - 4 \cdot 1 \cdot 0 = 12

m_{1, 2} = \frac{- ( - 12 ) \pm 12}{2 \cdot 1}

将解分隔开

m_{1} = \frac{- ( - 12 ) + 12}{2 \cdot 1}, m_{2} = \frac{- ( - 12 ) - 12}{2 \cdot 1}

m = \frac{- ( - 12 ) + 12}{2 \cdot 1} : 12

m = \frac{- ( - 12 ) - 12}{2 \cdot 1} : 0

二次方程组的解是:

m = 12, m = 0
