I can chat with you in Russian.

I'm sorry, I couldn't find any relevant information on the web for your query. It looks like you are trying to simplify an algebraic expression. Here is how I would do it:

(a-10)(10+a)+60-a^2

= a^2 - 10a + 10a - 100 + 60 - a^2

= -40

So, the simplified expression is -40. I hope this helps.Ответь+подробно.+Срочнооооо(a-10)(10+a)+60-a^2
