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

expand

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

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

Solution steps

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

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

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

(y + z)^{2}

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

(cos (t) - t cos (t))^{2}

\frac{3}{( x + 2 ) ( x - 1 )}

(1 - tan^{2} (x))^{2}
