expand (y(3x^2+y^2))/((x^2+y^2)^2)

expand

\frac{y ( 3 x ^{2} + y ^{2} )}{( x ^{2} + y ^{2} ) ^{2}}

\frac{3 y x ^{2} + y ^{3}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

Solution steps

\frac{y ( 3 x ^{2} + y ^{2} )}{( x ^{2} + y ^{2} ) ^{2}}

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

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

Expand

y (3 x^{2} + y^{2}) : 3 y x^{2} + y^{3}

= \frac{3 y x ^{2} + y ^{3}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

- 3 sin (2) (x + 5)
