expand (5x^2-4x+4)/((x^2+1)(x-2)(x+2))

expand

\frac{5 x ^{2} - 4 x + 4}{( x ^{2} + 1 ) ( x - 2 ) ( x + 2 )}

\frac{5 x ^{2} - 4 x + 4}{x ^{4} - 3 x ^{2} - 4}

Solution steps

\frac{5 x ^{2} - 4 x + 4}{( x ^{2} + 1 ) ( x - 2 ) ( x + 2 )}

Expand

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

= \frac{5 x ^{2} - 4 x + 4}{x ^{4} - 3 x ^{2} - 4}

\frac{( 2 + 2 cos ( θ ) ) ^{2}}{2}

\frac{d}{d Y} ((i) (L i + L Y))

\frac{y ( x - 2 ) ^{6}}{( x - 2 ) ^{6} + 4 y ^{6}}

(- 0, 16 + 0.33 j) (0.1 + 0.1 j)
