Explain the relationship between the polynomial identities: x^2 − 1 = (x +1)(x − 1) and x^2 − a^2 =(x − a)(x +a).

So these two equation can be related by identity

Step-by-step explanation:

We have given equation

And

We know the algebraic identity

From this identity

can be written as (x+1) (x-1)

And using same identity can be written as

So these two equation can be related by identity
