Answer 2

Answer :

$\large{\star\:\:(1.)\:\boxed{\bf{a\:=\:1}}\:\:\star}$

Explanation :

Given :–

• (x + 1) is a factor of cubic equation x³ + 3x² + 3x + a .

To Find :–

• The value of a .

Solution :–

We have ,

→ g(x) = x + 1 =0

→ x = (-1)

p(x) = x³+ 3x² + 3x + a

Putting x = (-1) , we get :

⇒ p(-1) = (-1)³ + 3(-1)² + 3(-1) + a = 0

⇒ (-1) + 3 - 3 + a = 0

⇒ a - 1 = 0

⇒ a = 1

∴ The value of a is 1 .
