expand (x^4+x^3+3x^2-4)/(x^3(x^2+4))

expand

\frac{x ^{4} + x ^{3} + 3 x ^{2} - 4}{x ^{3} ( x ^{2} + 4 )}

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

Solution steps

\frac{x ^{4} + x ^{3} + 3 x ^{2} - 4}{x ^{3} ( x ^{2} + 4 )}

Expand

x^{3} (x^{2} + 4) : x^{5} + 4 x^{3}

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

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

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

(x^{2} + y^{2} - 5) d x - (y + x y) d y
