ANSWER
Not a factor
EXPLANATION
The given polynomial has equation:
According to the remainder theorem, if (x+5) is a remainder, then f(-5)=0.
Let us substitute x=-5 into the function and evaluate to see if it will simplify to zero.
Since the remainder is not zero, x+5 is not a factor of
Answer:
(x+5) is NOT a factor of given function f(x).
Step-by-step explanation:
Given function is .
Now we need to determine if (x+5) is a factor of given function f(x) or not using either the remainder theorem or the factor theorem.
I'm going to use factor theorem which says that "If (x-c) is a factor of f(x) then f(c)=0"
so for (x+5) we have c=-5
Now we need to check if f(-5)=0 or not
which is not equal to 0.
Hence (x+5) is NOT a factor of given function f(x).
