Answer:

So these two equation can be related by identity [tex]x^2-a^2=(x+a)(x-a)[/tex]

Step-by-step explanation:

We have given equation [tex]x^2-1=(x+1)(x-1)[/tex]

And [tex]x^2-a^2=(x+a)(x-a)[/tex]

We know the algebraic identity [tex]a^2-b^2=(a+b)(a-b)[/tex]

From this identity

[tex]x^2-1[/tex] can be written as (x+1) (x-1)

And using same identity [tex]x^2-a^2[/tex] can be written as [tex](x-a)(x-b)[/tex]

So these two equation can be related by identity [tex]x^2-a^2=(x+a)(x-a)[/tex]
