Question

Given a polynomial f(x), if (x − 1) is a factor, what else must be true?

f(0) = 1
f(1) = 0
f(−1) = 0
f(0) = −1

Answer 1

Answer 2

x-1 is a factor,
which means if we put x= 1,
we get f(x) = 0

Answer 3

which is same as saying f(1) = 0

Answer 4

If x=1, you get f(1)=(1-1)*g(1)=0*g(1)=0
So, you get that f(1)=0 is true.

Answer 5

so B... Thank you so much :)
