expand (e^{-4x}+3x)/((x)(x^2+1))

expand

\frac{e ^{- 4 x} + 3 x}{( x ) ( x ^{2} + 1 )}

\frac{e ^{- 4 x} + 3 x}{x ^{3} + x}

Solution steps

\frac{e ^{- 4 x} + 3 x}{( x ) ( x ^{2} + 1 )}

Remove parentheses:

(a) = a

= \frac{e ^{- 4 x} + 3 x}{x ( x ^{2} + 1 )}

Expand

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

= \frac{e ^{- 4 x} + 3 x}{x ^{3} + x}

π (3 r + 8 s)^{2} \cdot (12 r + 32 s)

(f \circ g) 3 (- x + 7) - 2

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

(\frac{- x ^{2} + 8 x + 3}{4} - \frac{sin ( \frac{π x}{3} )}{2}) \cdot x

(a + b - \frac{a t}{10})^{2} \cdot t
