(x+a)/x+(x-2)/4 =0

解答

\frac{x + a}{x} + \frac{x - 2}{4} = 0

x = - 1 + - 4 a + 1, x = - - 4 a + 1 - 1

求解步骤

\frac{x + a}{x} + \frac{x - 2}{4} = 0

乘以最小公倍数

4 (x + a) + x (x - 2) = 0

解

4 (x + a) + x (x - 2) = 0 : x = - 1 + - 4 a + 1, x = - - 4 a + 1 - 1

x = - 1 + - 4 a + 1, x = - - 4 a + 1 - 1

\frac{2}{x - 3} - \frac{3}{x + 2} = 1

0 = \frac{1}{4 ( x ) + 2}

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

4 x^{2} - 16 x + 16 + \frac{4 x + 8}{x} = 0

\frac{x - 2}{5} = 1 - \frac{1}{2 x - 3}
