Answer:
4(2 - x)(2 + x)
Step-by-step explanation:
16 - 4x² ← factor out 4 from each term
= 4(4 - x²) ← difference of 2 squares
= 4(2 - x)(2 + x) ← in factored form
The answer is x = 3. I hope this helped

As (a+b)^2 = a^2 + 2*a*b +b^2 .......(i)
here we have
16z^2 + bz + 81 which can be written as (4z)^2 + bz +9^2
from (i) we can see that in order to be perfect square bz should be
bz = 2* (4z) * (9)
bz= 72z
dividing z on both sides we get
b=72
