Did I get this right? Simplifying a fraction

  • #1

Homework Statement


Simplify: (a2 + 2ab + b2)/(a2 - b2) times (a2 - 2ab + b2)/(a2 - b2)

Homework Equations


(a2 + 2ab + b2)/(a2 - b2) times (a2 - 2ab + b2)/(a2 - b2)

The Attempt at a Solution


Did I simplify this correctly?? (a+b)(a+b)/((a-b)(a+b)) times (a-b)(a-b)/((a-b)(a+b)) = ((a+b)/(a+b)) times ((a-b)/(a-b))
= (a+b)(a-b)/((a+b)(a-b)) = 1 times 1 = 1 Answer

That's the correct final result. It's hard to say if your steps are correct. You skipped some steps and regrouped things in some rather curious ways.
