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

expand

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

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

Solution steps

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

(x + 1)^{2} = x^{2} + 2 x + 1

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

cos^{2} ((a + k) \cdot t)

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

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

\frac{[ n ( n + 1 ) ( 2 ( n ) + 1 ) ]}{6} - n

2 (3 x - 1) e^{2 x + 1}
