2 (2 + 1)

Apply the distributive law:

a (b + c) = ab + a c

2 (2 + 1) = 22 + 2 \cdot 1

= 22 + 2 \cdot 1

Multiply the numbers:

2 \cdot 1 = 2

= 22 + 2

\frac{- 8 x ^{4} - 6 x + 4 x ^{5}}{( x ^{2} + 1 ) ^{4}}

(x e^{\frac{x}{2}} - 2 e^{\frac{x}{2}}) e^{x}

\frac{( s \cdot ( s + 0.5 ) \cdot ( s + 1 ) \cdot ( s ^{2} + 0.4 s + 4 ) )}{s + 4}

86 (68.8 s + \frac{10 s + 2057600}{s})
