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)

the anwser is missions

i do not believe this was true indefiantly the native americans would have lsot aganist america one they didndt have the resources and allies that america had and 2   indians werent as advanced at the time as they were not 3 americans had the expreince because some of the soliders from other wars fought in that war and were attecked etc
