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

simplify

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

- 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
