Factor the trinomial below.

Write each factor as a polynomial in descending order.

 

16x^2 - 0x - 1

 

Where does the 0 come into play, please explain if you can.

Factor the trinomial below. 

 

16x^2 - 0x - 1   

 

 

The zero coefficient on the center term makes it go away, leaving us with

 

16x2 – 1   which we immediately recognize as the difference of squares. 

 

the generality a2 – b2  always factors to (a+b)(a–b)   so in our specific problem 

 

16x2 – 1   factors to  (4x+1)(4x–1)   and there you have it.
