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]
