Answer 1

ЕСЛИ УРАВНЕНИЕ ТАКОЕ (2х+3у)(х-у)- х(х*у)ТО РЕШАТЬ ТАК:
(2х+3у)(х-у)- х(х*у)=2х²-2ху+3ху-3у²-х²-ху=х²-3у².
ЕСЛИ УРАВНЕНИЕ ТАКОЕ (2х+3у)(х-у)- х(х+у)ТО РЕШАТЬ ТАК:
(2х+3у)(х-у)- х(х+у)=2х²-2ху+3ху-3у²-х²-ху=х²-3у².

Answer 2

It seems there is a typographical error in your expression. The term "x(x=y)" doesn't appear to be a valid mathematical expression.

If you meant to write something different, please clarify, and I'll be happy to help you simplify or solve the expression.
