-x^2+300x=0

解答

- x^{2} + 300 x = 0

解答

x = 0, x = 300

求解步骤

- x^{2} + 300 x = 0

使用求根公式求解

x_{1, 2} = \frac{- 300 \pm 30 0 ^{2} - 4 ( - 1 ) \cdot 0}{2 ( - 1 )}

30 0^{2} - 4 (- 1) \cdot 0 = 300

x_{1, 2} = \frac{- 300 \pm 300}{2 ( - 1 )}

将解分隔开

x_{1} = \frac{- 300 + 300}{2 ( - 1 )}, x_{2} = \frac{- 300 - 300}{2 ( - 1 )}

x = \frac{- 300 + 300}{2 ( - 1 )} : 0

x = \frac{- 300 - 300}{2 ( - 1 )} : 300

二次方程组的解是:

x = 0, x = 300
