Решение неполных квадратных уравнений

a) 4x² - 9 = 0

4x² = 9

x² = 9/4

x = ±√(9/4)

x = ±3/2

x₁ = 1.5, x₂ = -1.5

б) -x² + 3 = 0

-x² = -3

x² = 3

x = ±√3

x₁ = √3, x₂ = -√3

в) -0,1x² + 10 = 0

-0,1x² = -10

x² = 100

x = ±√100

x₁ = 10, x₂ = -10

г) y² - 1/9 = 0

y² = 1/9

y = ±√(1/9)

y = ±1/3

y₁ = 1/3, y₂ = -1/3
