Answer 1

Answer:

Here's your answer in the attachment

Answer 2

Answer: The solutions are x= -4, x=4

Step-by-step explanation:

As per Property

a^2-b^2 = (a+b) (a-b)

Expressing the equation in Same manner:

x^2 -16= x^2-4^2

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

Now, we equate the factors to zero to obtain the Solution

x+4=0, x=0-4, X=-4 (Ans)

x-4=0, x=0+4, X = 4 (Ans)
