expand (-8n^2-8n-1)/((2n+1)^2)

expand

\frac{- 8 n ^{2} - 8 n - 1}{( 2 n + 1 ) ^{2}}

\frac{- 8 n ^{2} - 8 n - 1}{4 n ^{2} + 4 n + 1}

Solution steps

\frac{- 8 n ^{2} - 8 n - 1}{( 2 n + 1 ) ^{2}}

(2 n + 1)^{2} = 4 n^{2} + 4 n + 1

= \frac{- 8 n ^{2} - 8 n - 1}{4 n ^{2} + 4 n + 1}

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

U (t - π) cos (3 t)

r \cdot (r^{2} cos^{2} (θ) + r^{2} sin (θ) + 2 r sin (θ) + 1)

(2 cos (t) - 2 sin (t)) (- 2 sin (t))
