Answer 1

Answer:

$Let we consider the polynomial is f(x)So,f(x) = Now we have (x+1)Now we consider (x+1) is a factor of polynomial and x = -1Using factor theorem [f(x) = 1]The factor theorem say iff(x) = 0Then the (x+1) is a factor of polynomial f(x) but here it's equal to From this statement is not a factor of polynomial$
