Question

check weather -2 and 2 are zero of the polynomial x+2


give a image of a solution​

Answer 1

Answer:

only -2 is the zero of the polynomial x + 2

Step-by-step explanation:

Let's say,

= p(x) = x + 2

Substituting p(-2)

= p(-2) = (-2) + 2

= -2 + 2

= 0

Since, p(-2) = 0

-2 is the a zero of p(x)

And also,

Substituting p(2)

= p(2) = (2) + 2

= 2 + 2

= 4

Since, p(2) ≠ 0

2 is not a zero of p(x)
