simplify (1+3i)/(1+i)

Solution

simplify

\frac{1 + 3 i}{1 + i}

Solution

2 + i

Solution steps

\frac{1 + 3 i}{1 + i}

Multiply by the conjugate

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

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

Simplify

\frac{( 1 + 3 i ) ( 1 - i )}{( 1 + i ) ( 1 - i )} : \frac{4 + 2 i}{2}

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

Apply the fraction rule:

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

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

Simplify

\frac{4}{2} + \frac{2}{2} i : 2 + i

= 2 + i
