Answer 1

Answer:

can you please mark my answer as brainlist

Step-by-step explanation:

Let we consider the polynomial is f(x)

So,

f(x) =

Now we have (x+1)

Now we consider (x+1) is a factor of polynomial and x = -1

Using factor theorem [f(x) = 1]

The factor theorem say if

f(x) = 0

Then the (x+1) is a factor of polynomial f(x) but here it's equal to

From this statement is not a factor of polynomial
