expand (s+1)(s+2)(s+4)

expand

(s + 1) (s + 2) (s + 4)

s^{3} + 7 s^{2} + 14 s + 8

Solution steps

(s + 1) (s + 2) (s + 4)

Expand

(s + 1) (s + 2) (s + 4) : (s^{2} + 3 s + 2) (s + 4)

= (s^{2} + 3 s + 2) (s + 4)

Distribute parentheses

= s^{2} s + s^{2} \cdot 4 + 3 ss + 3 s \cdot 4 + 2 s + 2 \cdot 4

Simplify

s^{2} s + s^{2} \cdot 4 + 3 ss + 3 s \cdot 4 + 2 s + 2 \cdot 4 : s^{3} + 7 s^{2} + 14 s + 8

= s^{3} + 7 s^{2} + 14 s + 8

1 0^{2} \cdot 1 0^{3}
