expand s(s+0.5)(s+1)(s^2+0.4s+4)

expand

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

s^{5} + 1.9 s^{4} + 5.1 s^{3} + 6.2 s^{2} + 2 s

Solution steps

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

Expand

s (s + 0.5) (s + 1) (s^{2} + 0.4 s + 4) : s (s^{2} + 1.5 s + 0.5) (s^{2} + 0.4 s + 4)

= s (s^{2} + 1.5 s + 0.5) (s^{2} + 0.4 s + 4)

Expand

(s^{2} + 1.5 s + 0.5) (s^{2} + 0.4 s + 4) : s^{4} + 1.9 s^{3} + 5.1 s^{2} + 6.2 s + 2

= s (s^{4} + 1.9 s^{3} + 5.1 s^{2} + 6.2 s + 2)

Distribute parentheses

= s s^{4} + s \cdot 1.9 s^{3} + s \cdot 5.1 s^{2} + s \cdot 6.2 s + s \cdot 2

Simplify

s s^{4} + s \cdot 1.9 s^{3} + s \cdot 5.1 s^{2} + s \cdot 6.2 s + s \cdot 2 : s^{5} + 1.9 s^{4} + 5.1 s^{3} + 6.2 s^{2} + 2 s

= s^{5} + 1.9 s^{4} + 5.1 s^{3} + 6.2 s^{2} + 2 s
