expand (-3x-7)/((x+1)^3)

expand

\frac{- 3 x - 7}{( x + 1 ) ^{3}}

\frac{- 3 x - 7}{x ^{3} + 3 x ^{2} + 3 x + 1}

Solution steps

\frac{- 3 x - 7}{( x + 1 ) ^{3}}

(x + 1)^{3} = x^{3} + 3 x^{2} + 3 x + 1

= \frac{- 3 x - 7}{x ^{3} + 3 x ^{2} + 3 x + 1}

(1 + cot (θ)) (1 - tan (θ))

(4 x - \frac{2}{3}) (4 x + \frac{2}{3})

\frac{l}{s ( s + 2 )}

3 (1 + 3)
