expand ((x+2)^2)/((x+2j)(x-2))

expand

\frac{( x + 2 ) ^{2}}{( x + 2 j ) ( x - 2 )}

\frac{x ^{2} + 4 x + 4}{x ^{2} - 2 x + 2 j x - 4 j}

Solution steps

\frac{( x + 2 ) ^{2}}{( x + 2 j ) ( x - 2 )}

(x + 2)^{2} = x^{2} + 4 x + 4

= \frac{x ^{2} + 4 x + 4}{( x + 2 j ) ( x - 2 )}

Expand

(x + 2 j) (x - 2) : x^{2} - 2 x + 2 j x - 4 j

= \frac{x ^{2} + 4 x + 4}{x ^{2} - 2 x + 2 j x - 4 j}

\frac{( x ^{2} )}{( x - 1 ) ( x - 2 )}

\frac{( k + 1 ) ^{3}}{3}
