Question

check weather 4 and -4 are zeros of the polynomial x-4​

Answer 1

Answer:

4 is its zero but not -4

Step-by-step explanation:

p(4) = 4-4 = 0

p(-4) = -4-4 = -8

Answer 2

Given f(x)= x-4
By remainder theorem if 4&-4 are zeroes of f(x) then f(4)=4-4=0
f(-4)=-4-4=-8
So 4 is the zer of the polynomial x-4 but -4 is not it’s zero
