p(x) = x3 + 2x2 + 3x + 2= x3 + x2 + x2 + x + 2x + 2 (2x2 = x2 + x2 and 3x = x + 2x)= x2 (x + 1) + x (x + 1) + 2 (x + 1)= (x + 1) (x2 + x + 2)

Factorize the fol

Answer :

p(x) = x³ + 2x² + 3x + 2

= x³ + x² + x² + x + 2x + 2 (2x² = x² + x² and 3x = x + 2x)

= x² (x + 1) + x (x + 1) + 2 (x + 1)

= (x + 1) (x² + x + 2)
