expand-(y(12x+5y))/(x(4x+5y))

expand

- \frac{y ( 12 x + 5 y )}{x ( 4 x + 5 y )}

- \frac{12 y x + 5 y ^{2}}{4 x ^{2} + 5 y x}

Solution steps

- \frac{y ( 12 x + 5 y )}{x ( 4 x + 5 y )}

Expand

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

= - \frac{y ( 5 y + 12 x )}{4 x ^{2} + 5 y x}

Expand

y (12 x + 5 y) : 12 y x + 5 y^{2}

= - \frac{5 y ^{2} + 12 y x}{4 x ^{2} + 5 y x}

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