expand (x^2+2x-18)/((x+4)x^3)

expand

\frac{x ^{2} + 2 x - 18}{( x + 4 ) x ^{3}}

\frac{x ^{2} + 2 x - 18}{x ^{4} + 4 x ^{3}}

Solution steps

\frac{x ^{2} + 2 x - 18}{( x + 4 ) x ^{3}}

Expand

(x + 4) x^{3} : x^{4} + 4 x^{3}

= \frac{x ^{2} + 2 x - 18}{x ^{4} + 4 x ^{3}}

x^{\frac{1}{3}} (x - 2)

(x + a) (x + b) - x

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

(t sin (t)) \cdot (sin (t) + t cos (t))

\frac{1 - e ^{- s}}{s ( s ^{2} + 2 s + 26 )}
