expand ((3+4j)(1-2j))/(2j+4)

expand

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

\frac{3 - 2 j - 8 j ^{2}}{2 j + 4}

Solution steps

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

Expand

(3 + 4 j) (1 - 2 j) : 3 - 2 j - 8 j^{2}

= \frac{3 - 2 j - 8 j ^{2}}{2 j + 4}

(4 - x) ln (x + 5)

(x - 2 + 1)^{2}

\frac{( s + 2 )}{s ( s + 1 ) ( s + 3 ) ( s + 5 )}

(7 + \frac{i}{n})^{2}

\frac{k}{z - a z + b ( 1 - a )}
