simplify (9+5i)/(1+i)

Solution

simplify

\frac{9 + 5 i}{1 + i}

Solution

7 - 2 i

Solution steps

\frac{9 + 5 i}{1 + i}

Multiply by the conjugate

\frac{1 - i}{1 - i}

= \frac{( 9 + 5 i ) ( 1 - i )}{( 1 + i ) ( 1 - i )}

Simplify

\frac{( 9 + 5 i ) ( 1 - i )}{( 1 + i ) ( 1 - i )} : \frac{14 - 4 i}{2}

= \frac{14 - 4 i}{2}

Apply the fraction rule:

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

= \frac{14}{2} + \frac{- 4}{2} i

Simplify

\frac{14}{2} + \frac{- 4}{2} i : 7 - 2 i

= 7 - 2 i
