simplify

\frac{2 i}{( 1 + i )}

1 + i

Solution steps

\frac{2 i}{1 + i}

Multiply by the conjugate

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

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

Simplify

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

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

Rewrite in standard complex form:

1 + i

= 1 + i

- 25 - - 16

\frac{x}{25} = \frac{7}{10}

x^{3} + 5 x^{2} - 4 x - 20 \geq 0

2 x^{2} < 3 x + 7

0 = - 5 x - 5
