expand (8s)/((x+1)(x-1)(x^2+4x+5))

expand

\frac{8 s}{( x + 1 ) ( x - 1 ) ( x ^{2} + 4 x + 5 )}

\frac{8 s}{x ^{4} + 4 x ^{3} + 4 x ^{2} - 4 x - 5}

Solution steps

\frac{8 s}{( x + 1 ) ( x - 1 ) ( x ^{2} + 4 x + 5 )}

Expand

(x + 1) (x - 1) (x^{2} + 4 x + 5) : x^{4} + 4 x^{3} + 4 x^{2} - 4 x - 5

= \frac{8 s}{x ^{4} + 4 x ^{3} + 4 x ^{2} - 4 x - 5}

\frac{x + e ^{x} ( 4 + x ^{2} )}{e ^{x} + 4}

(e^{- 5 t} - e^{2 t})^{2}

\frac{5 a + 5}{4} - \frac{3 - 7 a}{6}

e (t - 2.36)

so l v e (- 1575000 + \frac{x}{1 + ( 0.2139600000000 \dots ) ^{2}} = 0)
