Answer 1

Answer:

Let f(u)=4u

2 +8u

To calculate the zeros of the given equation, put f(u)=0.

4u 2 +8u=0

4u(u+2)=0

u=0,u=−2

The zeros of the given equation is 0 and −2.

Sum of the zeros is 0+(−2)=−2.

Product of the zeros is 0×−2=0.

According to the given equation,

The sum of the zeros is,

a−b = 4−(8)=−2
