50x-(1/(100x))=8

解答

50 x - (\frac{1}{100 x}) = 8

解答

x = \frac{4 2 + 33}{50 2}, x = \frac{4 2 - 33}{50 2}

+1

十进制

x = 0.16124 \dots, x = - 0.00124 \dots

求解步骤

50 x - (\frac{1}{100 x}) = 8

化简

- (\frac{1}{100 x}) : - \frac{1}{100 x}

50 x - \frac{1}{100 x} = 8

在两边乘以

x

50 x^{2} - \frac{1}{100} = 8 x

解

50 x^{2} - \frac{1}{100} = 8 x : x = \frac{4 2 + 33}{50 2}, x = \frac{4 2 - 33}{50 2}

x = \frac{4 2 + 33}{50 2}, x = \frac{4 2 - 33}{50 2}

验证解

找到无定义的点（奇点）:

x = 0

将不在定义域的点与解相综合:

x = \frac{4 2 + 33}{50 2}, x = \frac{4 2 - 33}{50 2}

流行的例子

\frac{3 ( 9 - 2 x )}{x} = x

1/x-(2x)/(x+1)=0

\frac{1}{x} - \frac{2 x}{x + 1} = 0

\frac{x ^{2} + 2}{x} = x + 2

x^{-2}+2x^{-1}-24=0

x^{- 2} + 2 x^{- 1} - 24 = 0

\frac{2}{3 m + 2} = 0
