化简 (-4i-1)/(-2i)

解答

化简

\frac{- 4 i - 1}{- 2 i}

2 - \frac{1}{2} i

求解步骤

\frac{- 4 i - 1}{- 2 i}

将

- 4 i - 1

改写成标准复数形式:

- 1 - 4 i

= \frac{- 1 - 4 i}{- 2 i}

乘以共轭根式

\frac{- i}{- i}

= \frac{( - 1 - 4 i ) ( - i )}{- 2 i ( - i )}

化简

\frac{( - 1 - 4 i ) ( - i )}{- 2 i ( - i )} : \frac{i - 4}{- 2}

= \frac{i - 4}{- 2}

Rewrite in standard complex form:

2 - \frac{1}{2} i

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

2 (v - 3) - 5 v = - 3 (v + 3)

(7 - x) (3 x + 1) (x - 2) \leq 0
