Simplifying a rational expression

Click For Summary
SUMMARY

The discussion focuses on simplifying the rational expression \(\frac{2(x-1)^2}{(x^2-1)^2}\) to \(\frac{2}{(x+1)^2}\). The key step involves recognizing that \(x^2-1\) can be factored as \((x-1)(x+1)\), a technique known as the Difference of Squares. This factorization is crucial for reducing the expression correctly. The simplification process highlights the importance of factoring in calculus problems.

I've done a calculus problem. The LHS is my answer and the RHS is the answer in the book.

[tex]\frac{2(x-1)^2}{(x^2-1)^2} = \frac{2}{(x+1)^2}[/tex]

What was done to simplify this equation?

x2-1=(x-1)(x+1)
 
I believe it was called the Difference of Squares. Factor it out and try again.
