Simplifying formulas with factorials (2n-1)

Click For Summary
SUMMARY

The discussion focuses on simplifying the factorial expression (2n+1)! and clarifies that it is not equivalent to (2n-1)!. The correct simplification is provided as (2n + 1)! = (2n + 1)(2n)(2n - 1)!. This establishes a clear distinction between the two factorials and emphasizes the importance of understanding factorial notation in mathematical expressions.

How would you simplify (2n+1)!
Is the same as (2n-1)! ?

That's about as simple is it can be made.

No, since (2n + 1)! = (2n + 1)(2n)(2n - 1)!
