Question

s^3 + 6s^2 + 18s + 20​

Answer 1

Bhai question Kya hai krna kya hai isme

Answer 2

${s}^{3} + 6 {s}^{2} + 18s + 20$

we can factories it.

= s^3 + 2s^2 +4s^2 + 8s +10s + 20

= s^2 × (s+2) + 4s × (s+2) 10(s+2)

(s+2) as a common factor...

therefore...

= (s+2) × (s^2 + 4s + 10)

Hence Factorised!
