1) 15ху² - 25у²/ 5 ху = 5ху²(3у - 5 у) / 5ху = у( 3х - 5) 2) 24 х² + 6 ух / 27ху = 3х( 8х + 2у) / 3х ( 9у) = 8х+2у / 9 у 3) 40у² / 32у³ - 12ху= 4у ( 10у) / 4у ( 8у² - 3х)= 10у / 8у² - 3х 4) 14 uv / 21 uv² - 21v² = 7v (2u) / 7v ( 3uv - 3v)= 2u / 3uv - 3v 5)4y² / 10ху - 14у= 2у( 2у) / 2у( 5х-7)= 2у /5х -7
