-4x^2+32x-64=0

解

- 4 x^{2} + 32 x - 64 = 0

x = 4

解答ステップ

- 4 x^{2} + 32 x - 64 = 0

解くとthe二次式

x_{1, 2} = \frac{- 32 \pm 3 2 ^{2} - 4 ( - 4 ) ( - 64 )}{2 ( - 4 )}

3 2^{2} - 4 (- 4) (- 64) = 0

x_{1, 2} = \frac{- 32 \pm 0}{2 ( - 4 )}

x = \frac{- 32}{2 ( - 4 )}

\frac{- 32}{2 ( - 4 )} = 4

x = 4

二次equationの解:

x = 4
