ANSWER

The given expression is
16 {x}^{2}  - 1


This expression can be rewritten as,

16 {x}^{2}  + 0x - 1

By comparing to
a{x}^{2}  + bx + c
a=16,b=0,c=-1
ac =  - 16


Two numbers that we multiply to get
- 16
and add to get zero are
- 4 \: and \: 4




The factored form is


16 {x}^{2}  - 4x  + 4x- 1


4x(4x - 1)  +1( 4x- 1)

(4x + 1)(4x - 1)



We factor further to get,
