Verified answer

X² - 10x < -16
x² - 10x + 16 < 0 Решаем квадратное уравнение
   х² -10х + 16 = 0 D = b²- 4ac = 100 - 64 = 36
   x₁ = (-b+√D)/2a = 8
   x₂ = (-b-√D)/2a = 2

Таким образом, х² - 10х + 16 = (х - 8)(х - 2)
(х - 8)(х - 2) < 0

Решаем 2 системы: { x - 8 < 0    { x - 8 > 0
   {x - 2 > 0 { x - 2 < 0

   { x < 8 { x > 8
   { x > 2 { x < 2

Решение первой системы х ∈ (2; 8)      Вторая система решения не имеет

Ответ: х ∈ (2; 8)
