expand ((s+1)(s+0.5)(s+2))*28

expand

((s + 1) \cdot (s + 0.5) \cdot (s + 2)) \cdot 28

28 s^{3} + 98 s^{2} + 98 s + 28

Solution steps

((s + 1) (s + 0.5) (s + 2)) \cdot 28

Remove parentheses:

(a) = a

= (s + 1) (s + 0.5) (s + 2) \cdot 28

= 28 (s + 1) (s + 0.5) (s + 2)

Expand

(s + 1) (s + 0.5) : s^{2} + 1.5 s + 0.5

= 28 (s^{2} + 1.5 s + 0.5) (s + 2)

Expand

(s^{2} + 1.5 s + 0.5) (s + 2) : s^{3} + 3.5 s^{2} + 3.5 s + 1

= 28 (s^{3} + 3.5 s^{2} + 3.5 s + 1)

Expand

28 (s^{3} + 3.5 s^{2} + 3.5 s + 1) : 28 s^{3} + 98 s^{2} + 98 s + 28

= 28 s^{3} + 98 s^{2} + 98 s + 28

((x + 2)^{\frac{1 - x}{x}} - x^{\frac{- 2 x + 1}{x}}) \cdot x
