-16x^2+16x+32=0

解答

- 16 x^{2} + 16 x + 32 = 0

解答

x = - 1, x = 2

求解步骤

- 16 x^{2} + 16 x + 32 = 0

使用求根公式求解

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 ( - 16 ) \cdot 32}{2 ( - 16 )}

1 6^{2} - 4 (- 16) \cdot 32 = 48

x_{1, 2} = \frac{- 16 \pm 48}{2 ( - 16 )}

将解分隔开

x_{1} = \frac{- 16 + 48}{2 ( - 16 )}, x_{2} = \frac{- 16 - 48}{2 ( - 16 )}

x = \frac{- 16 + 48}{2 ( - 16 )} : - 1

x = \frac{- 16 - 48}{2 ( - 16 )} : 2

二次方程组的解是:

x = - 1, x = 2
