expand (x+y)/((x+y)^2+1)

expand

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

\frac{x + y}{x ^{2} + 2 x y + y ^{2} + 1}

Solution steps

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

Expand

(x + y)^{2} + 1 : x^{2} + 2 x y + y^{2} + 1

= \frac{x + y}{x ^{2} + 2 x y + y ^{2} + 1}

9 \cdot 895

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

(- 6, - 3) y (3, 0)

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

\frac{( 1 - 2 θ ) ^{2}}{2}
