Answer:
These two equations are related to each other by identity [tex]a^2-b^2=(a+b)(a-b)[/tex]
Step-by-step explanation:
We have given equations
[tex]\frac{x^2-1}{x+1}[/tex]
We know the algebraic identity
[tex]a^2-b^2=(a+b)(a-b)[/tex]
So [tex]a^2-1^2=(x+1)(x-1)[/tex]
So [tex]\frac{x^2-1}{x+1}=\frac{(x+1)(x-1)}{x+1}=(x-1)[/tex]
So these two equations are related to each other by algebraic identity [tex]a^2-b^2=(a+b)(a-b)[/tex]
