Solution

simplify

\frac{3}{1 + i}

Solution

\frac{3}{2} - \frac{3}{2} i

Solution steps

\frac{3}{1 + i}

Multiply by the conjugate

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

= \frac{3 ( 1 - i )}{( 1 + i ) ( 1 - i )}

Simplify

\frac{3 ( 1 - i )}{( 1 + i ) ( 1 - i )} : \frac{3 - 3 i}{2}

= \frac{3 - 3 i}{2}

Rewrite in standard complex form:

\frac{3}{2} - \frac{3}{2} i

= \frac{3}{2} - \frac{3}{2} i
