What is expand (x(25-4x^2-4y^2))/(y(4x^2+4y^2+25)) ?

The solution to expand (x(25-4x^2-4y^2))/(y(4x^2+4y^2+25)) is (25x-4x^3-4xy^2)/(4x^2y+4y^3+25y)

expand (x(25-4x^2-4y^2))/(y(4x^2+4y^2+25))

expand

\frac{x ( 25 - 4 x ^{2} - 4 y ^{2} )}{y ( 4 x ^{2} + 4 y ^{2} + 25 )}

\frac{25 x - 4 x ^{3} - 4 x y ^{2}}{4 x ^{2} y + 4 y ^{3} + 25 y}

Solution steps

\frac{x ( 25 - 4 x ^{2} - 4 y ^{2} )}{y ( 4 x ^{2} + 4 y ^{2} + 25 )}

Expand

y (4 x^{2} + 4 y^{2} + 25) : 4 x^{2} y + 4 y^{3} + 25 y

= \frac{x ( 25 - 4 x ^{2} - 4 y ^{2} )}{4 x ^{2} y + 4 y ^{3} + 25 y}

Expand

x (25 - 4 x^{2} - 4 y^{2}) : 25 x - 4 x^{3} - 4 x y^{2}

= \frac{25 x - 4 x ^{3} - 4 x y ^{2}}{4 x ^{2} y + 4 y ^{3} + 25 y}

(x - 5 i)^{2}

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

\frac{( tan ( x ) + sin ( x ) ) cos ( x )}{csc ( x ) + cot ( x )}

\frac{n !}{n ( n - 1 )}

\frac{d}{d t} ((x (t, r)) (r (t - sin (t))))
