Not sure what "factor theorem" refers to, but one theorem it might be another name for could be the polynomial remainder theorem. It says that a polynomial [tex]p(x)[/tex], when divided by a linear binomial [tex]x-c[/tex], leaves a remainder whose value is [tex]p(c)[/tex]. If the remainder is 0, then [tex]x-c[/tex] is a factor of [tex]p(x)[/tex].
In this case, for [tex]v+5=v-(-5)[/tex] to be a factor of [tex]p(v)=v^4+16v^3+8v^2-725[/tex], we need to check
[tex]p(-5)=(-5)^4+16(-5)^3+8(-5)^2-725=-1900\neq0[/tex]
So [tex]v+5[/tex] is not a factor of [tex]v^4+16v^3+8v^2-725[/tex].

Answer:
By factor theorem (v+5) is not a factor of the given polynomial f(v).
Step-by-step explanation:
The factor theorem states that
- f(x) has a factor (x-k) if and only if f(k) = 0
We are given the following information:
[tex]f(v) = v^4 + 16v^3 + 8v^2 - 725[/tex]
We have to check whether (v+5) is a factor of given polynomial.
[tex](v+5) = (v-(-5))\\f(-5) = (-5)^4 + 16(-5)^3 + 8(-5)^2 - 725 = -1900\\f(-5) \neq 0[/tex]
Hence, by factor theorem (v+5) is not a factor of the given polynomial f(v).
