Question

. Verify that -2 is a zero of the polynomial p(a)=a+2

Answer 1

a+2=0

if 2 goes to right side then symbol becomes into minus.

a=-2

Therefore the answer is -2.

Answer 2

Step-by-step explanation:

if -2 is the zero of the polynomial then

p(-2)= 0

p(-2)= a+2

since p(-2) =0

0=a+2

a= -2
