Question

check -2 and 2 are the 0 of the polynomial x+2​

Answer 1

p(x)=x+2

x=-2

x+2=0

-2+2=0

-2 is zero of given polynomial

x+2=0

2+2=4

2 is not zero of polynomial

Answer 2

let f(x)=x+2

f(2)=2+2=4

f(2)!= 0

f(-2)=-2+2=0

hence -2 is a zero for x+2.........bs x ki jagah par 2 aur -2 rakh 0 a gya to zero h nhi to nhi h
