Question

In the quadratic polynomial x²-16,sum of the zeroes is
​

Answer 1

Answer:

X2-16=(X+4)(X-4)=there are two roots +4 and - 4,so sum of roots =0

Answer 2

Answer:

sum of the zeroes is= 0

Step-by-step explanation:

x^2 - 16

=(x)^2 - (4)^2

=(x+4) (x-4)

(x+4)=0

x=(-4)

(x-4)=0

x= 4

sum of the zeroes

(-4+4)= 0 answer.
