Question

check whether -2 and 2 are zeros of polynomial p(x)=x+2​

Answer 1

Answer:

only -2 is the zero of polynomial

Step-by-step explanation:

acc. to ques.,

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

p(2)=2+2=4(which cannot be equal to zero)

hope it helpa

Answer 2

Answer:

-2 is the zero

Step-by-step explanation:

x+2-----eqn-1

substituting the value of x in the eqn-1

-2+2= 0

so we can say that -2 is the for the given polynomial

where as when we substitute 2 it will be

2+2=4

which is non-zero

thus we can say that 2 isn't the zero of the polynomial whereas -2 is
