Answer 2

I can help you with this question. The expression (a2-2b)2 can be simplified by using the formula (x-y)2 = x2-2xy+y2, where x = a and y = 2b. Then we have:

(a2-2b)2 = (a-2b)2 = a2-2a(2b)+(2b)2 = a2-4ab+4b2

This is the final answer. You can also use an online calculator to simplify expressions, such as [this one](https://allcalc.ru/node/1825). If you need a translation, you can use [Google Translate](https://translate.google.ru/?hl=en&tab=wT&authuser=0). I hope this helps.
