expand s(s+3)(s+4)(s+8)

expand

s (s + 3) (s + 4) (s + 8)

s^{4} + 15 s^{3} + 68 s^{2} + 96 s

Solution steps

s (s + 3) (s + 4) (s + 8)

Expand

s (s + 3) (s + 4) (s + 8) : s (s^{2} + 7 s + 12) (s + 8)

= s (s^{2} + 7 s + 12) (s + 8)

Expand

s (s + 8) : s^{2} + 8 s

= (s^{2} + 8 s) (s^{2} + 7 s + 12)

Distribute parentheses

= s^{2} s^{2} + s^{2} \cdot 7 s + s^{2} \cdot 12 + 8 s s^{2} + 8 s \cdot 7 s + 8 s \cdot 12

Simplify

s^{2} s^{2} + s^{2} \cdot 7 s + s^{2} \cdot 12 + 8 s s^{2} + 8 s \cdot 7 s + 8 s \cdot 12 : s^{4} + 15 s^{3} + 68 s^{2} + 96 s

= s^{4} + 15 s^{3} + 68 s^{2} + 96 s
