化简 (8-2i)/(-4+i)

解答

化简

\frac{8 - 2 i}{- 4 + i}

- 2

求解步骤

\frac{8 - 2 i}{- 4 + i}

乘以共轭根式

\frac{- 4 - i}{- 4 - i}

= \frac{( 8 - 2 i ) ( - 4 - i )}{( - 4 + i ) ( - 4 - i )}

化简

\frac{( 8 - 2 i ) ( - 4 - i )}{( - 4 + i ) ( - 4 - i )} : \frac{- 34}{17}

= \frac{- 34}{17}

数字相除:

\frac{- 34}{17} = - 2

= - 2

- 7 = - 6 x + 7 x - 7

s im pl i f y (5 + 3) (2 - 3)

f a c t or 2 y^{2} - 3 y - 5

2 + 3 (x + 2 x) = - 2 x (2 - 4) + 1

- 2 + m > - 3
