Ответ:
х * (х + 3)
Объяснение:
(х + 3)² - 3 * (х + 3) = (х + 3) * (х + 3 - 3) =
(х + 3) * х = х * (х + 3)
(х+3)² - 3(х+3) = (х+3)(х + 3 - 3) = х(х+3)

Ответ:
х * (х + 3)
Объяснение:
(х + 3)² - 3 * (х + 3) = (х + 3) * (х + 3 - 3) =
(х + 3) * х = х * (х + 3)
(х+3)² - 3(х+3) = (х+3)(х + 3 - 3) = х(х+3)
