x^2-16x-192=0

解答

x^{2} - 16 x - 192 = 0

解答

x = 24, x = - 8

求解步骤

x^{2} - 16 x - 192 = 0

使用求根公式求解

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 1 \cdot ( - 192 )}{2 \cdot 1}

(- 16)^{2} - 4 \cdot 1 \cdot (- 192) = 32

x_{1, 2} = \frac{- ( - 16 ) \pm 32}{2 \cdot 1}

将解分隔开

x_{1} = \frac{- ( - 16 ) + 32}{2 \cdot 1}, x_{2} = \frac{- ( - 16 ) - 32}{2 \cdot 1}

x = \frac{- ( - 16 ) + 32}{2 \cdot 1} : 24

x = \frac{- ( - 16 ) - 32}{2 \cdot 1} : - 8

二次方程组的解是:

x = 24, x = - 8

- 5 x^{2} - 6 x = - 1 + 2 x

- 2 x^{2} + 72 = 0

6 x^{2} + 36 x - 42 = 0

- 6 x^{2} - 8 x = 0
