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

expand

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

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

Solution steps

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

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

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

Expand

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

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

(4 x - \frac{x ^{3}}{5}) d x

e^{x - 1} \cdot (x^{2} + 8 (x) - 12)

\frac{k ^{2} + 7 k - 8}{( k + 6 ) ( k - 8 )}

d (3 sec (x) - ln (x))

\frac{d}{d t} ((x) (2 x^{2} + 2))
