Question

Check whether -2 and 2 are 0 of the polynomial x+2​

Answer 1

Answer:

Step-by-step explanation:

x=-2

-2+2=0

x=2

2+2=4

therefore x=-2 is the only zero of (x+2)

Answer 2

Answer:

-2 is a zero , but 2 is not..

Step-by-step explanation:

p(x)= x+2

when x= 2 ,

p(2)= 2+2 = 4

so x = 2 is not a zero of this polynomial

when x= -2 ,

p(-2)= -2+2=0

so x = -2 is a zero of the polynomial
