化简 (-26-26i)/(-6+4i)

解答

化简

\frac{- 26 - 26 i}{- 6 + 4 i}

1 + 5 i

求解步骤

\frac{- 26 - 26 i}{- 6 + 4 i}

乘以共轭根式

\frac{- 6 - 4 i}{- 6 - 4 i}

= \frac{( - 26 - 26 i ) ( - 6 - 4 i )}{( - 6 + 4 i ) ( - 6 - 4 i )}

化简

\frac{( - 26 - 26 i ) ( - 6 - 4 i )}{( - 6 + 4 i ) ( - 6 - 4 i )} : \frac{52 + 260 i}{52}

= \frac{52 + 260 i}{52}

使用分式法则:

\frac{a + bi}{c} = \frac{a}{c} + \frac{b}{c} i

= \frac{52}{52} + \frac{260}{52} i

化简

\frac{52}{52} + \frac{260}{52} i : 1 + 5 i

= 1 + 5 i

s im pl i f y - \frac{2}{3} c - \frac{9}{5} + 14 c + \frac{3}{10}

s im pl i f y 1 - \frac{0.1}{2}

s im pl i f y \frac{( x ^{2} - 5 x + 6 )}{( x - 2 )}

s im pl i f y \frac{5}{8} + \frac{1}{6}

d o main f (b) = \frac{b ^{2} + b - 30}{3 b ^{2} + 18 b}
