(3х-1)*(x+2)=0
3х-1=0 х+2=0
3х=1 х=-2
х1=1/3
Решение
- x² + 6x - 6 = 0
x² - 6x + 6 = 0
D = 36 - 4*1*6 = 12
x₁ = (6 - √12)/2
x₁ = (6 - 2√3)/2
x₁= 3 - √3
x₂ = (6 +√12)/2
x₂ = (6 + 2√3)/2
x₂ = 3 + √3

Ответ: 5; -13; -9
Пошаговое объяснение:
1целая 1/2 × (-5) × (-2/3) = 3/2 × (-2/3) × (-5) = -1 × (-5) = 5
3/8 × (-13) × 2целых 2/3 = 3/8 × 8/3 × (-13) = 1 × (-13) = -13
-1целая 3/7 × (-9) × (-7/10) = -10/7 × (-7/10) × (-9) = 1 × (-9) = -9
