Question

verify that 4 is a zero of the polynomial p into x equal to x minus 4.​

Answer 1

Answer:

x-4=0 put x=4 then 4-4=0

Answer 2

Given polynomial,

p(x) = x - 4

If 4 is a zero of the polynomial then p(4) should be equal to zero.

Put x = 4

p(4) = 4 - 4

= 0

=> p(4) = 0

Hence 4 is a zero of the polynomial.
