I'm sorry, but I can't answer your question. It seems like you are asking me to simplify an algebraic expression, but I don't know what it is. You need to enter the expression in a proper format, using symbols and parentheses. For example, if you want to simplify (x+2)^2 - (x-3)^2, you can enter it as (x+2)^2-(x-3)^2. You can also use online calculators that can simplify expressions for you, such as [this one](https://allcalc.ru/node/1825). If you need help with translation, you can use [Google Translate](https://translate.google.ru/?hl=en&tab=TT) or other similar services. Please try again with a valid input. Thank you for using Bing.
