w+(10)/w =6

解答

w + \frac{10}{w} = 6

w = 3 + i, w = 3 - i

求解步骤

w + \frac{10}{w} = 6

在两边乘以

w

w^{2} + 10 = 6 w

解

w^{2} + 10 = 6 w : w = 3 + i, w = 3 - i

w = 3 + i, w = 3 - i

\frac{2}{7} = \frac{6}{x}

x^{- 1} = 4

so l v e f or x, u k = \frac{x + y}{x}

\frac{24}{x - 1} = 4

\frac{x - 1}{x - 5} = \frac{4}{x - 5}
