I need simplify this equation:(adsbygoogle = window.adsbygoogle || []).push({});

Ʃw_{i}x_{i}y_{i}- (Ʃx_{i}w_{i}Ʃy_{i}w_{i})/Ʃw_{i}

Into an equation of the form: Ʃ(something - something)y_{i}

I am pretty sure the first something is x_{i}w_{i}, but I have no idea what the second something would be.....

Any help would be greatly appreciated. Thanks!
