x+1/x =0

解答

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

x = i, x = - i

求解步骤

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

在两边乘以

x

x^{2} + 1 = 0

解

x^{2} + 1 = 0 : x = i, x = - i

x = i, x = - i

so l v e f or \frac{8}{y} - 1 = x + 3, y

\frac{x ^{2} + x - 6}{x - 2} = x + 3

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

a = \frac{1}{2 h ( b ^{1} + b ^{2} )}

x = 1 + \frac{1}{x}
