I'm trying to find an integration reduction formula for the following equation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

{{I}_n}=\int _{0}^{2}{{\big(4-{x^2}\big)}^n}\delta x

[/tex]

Any indication on how to begin would be much appreciated as I've tried many different approaches but all have ended in failure.

Thanks
