Question

Given a polynomial f(x), if (x + 2) is a factor, what else must be true?

Answer 1

according to remainder theorem,if f(x) is a polynomial with (x+2) as a factor then f(-2) must be equal to zero.

Answer 2

f(0) = 2

f(0) = -2

f(2) = 0

f(-2) = 0

so the answer is B

Answer 3

no,f(-2)=0 is the ans

Answer 4

is the answer B

Answer 5

Rishi123 is using the idea

if (x-k) is a factor of P(x), then P(k) = 0

Answer 6

in this case, k = -2

Answer 7

so the answer id D

Answer 8

is
