expand (s-r+1)/((r+1)^2)

expand

\frac{s - r + 1}{( r + 1 ) ^{2}}

\frac{s - r + 1}{r ^{2} + 2 r + 1}

Solution steps

\frac{s - r + 1}{( r + 1 ) ^{2}}

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

= \frac{s - r + 1}{r ^{2} + 2 r + 1}

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

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

(1 - y^{2}) d y

(\frac{sin ( 2 x )}{y} + x) d x

(\frac{sin ( 2 x )}{y} + x) d y
