simplify (4-2i)/(1+i)

Solution

simplify

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

Solution

1 - 3 i

Solution steps

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

Multiply by the conjugate

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

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

Simplify

\frac{( 4 - 2 i ) ( 1 - i )}{( 1 + i ) ( 1 - i )} : \frac{2 - 6 i}{2}

= \frac{2 - 6 i}{2}

Apply the fraction rule:

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

= \frac{2}{2} + \frac{- 6}{2} i

Simplify

\frac{2}{2} + \frac{- 6}{2} i : 1 - 3 i

= 1 - 3 i
