(х + 3)(х - 10) < (х - 5)(х - 2)
(х + 3)(х - 10) - (х - 5)(х - 2) = х² - 10х + 3х - 30 - х² + 2х + 5х - 10 =
= - 40 < 0
Значит, (х + 3)(х - 10) < (х - 5)(х - 2).
(х + 3)(х - 10) < (х - 5)(х - 2)
(х + 3)(х - 10) - (х - 5)(х - 2) = х² - 10х + 3х - 30 - х² + 2х + 5х - 10 =
= - 40 < 0
Значит, (х + 3)(х - 10) < (х - 5)(х - 2).
