Need with question 3 just want to ensure my answer is correct before continuing

B. -3

The value of a for given polynomial is -3

Factor theorem for polynomials,

If (x-c) is a factor of polynomial f(x), then f(c)=0

Given: x+a is a factor of polynomial

Let

By Factor theorem, since x+a is a factor of f(x),

Substituting in f(x)=0, we get

Therefore, value of a is (-3)
