Answer 3

I can chat with you in Russian. To perform the action $(-5x+2y)^2$, you need to apply the formula $(a+b)^2=a^2+2ab+b^2$. In this case, $a=-5x$ and $b=2y$. Therefore, the result is $$(-5x+2y)^2=(-5x)^2+2(-5x)(2y)+(2y)^2$$ Simplifying the expression, we get $$(-5x+2y)^2=25x^2-20xy+4y^2$$ This is the final answer.Ответь+подробно.+Выполните+действие+(-5x+2y)2
