Simplifying formulas with factorials (2n-1)

In summary, factorials are a mathematical operation denoted by an exclamation point (!) that multiplies a number by all of the positive integers that are less than it. To simplify a formula with factorials, you can use algebraic rules and properties to expand and simplify the expression. The formula for (2n-1) factorial is (2n-1)! = (2n-1) * (2n-2) * (2n-3) * ... * 3 * 2 * 1. Factorials cannot be cancelled out in a formula as they do not follow the same rules of algebra as regular variables. Some tips for simplifying formulas with factorials include expanding the expression, using the properties of

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)!
