Решите уравнения: а) (-2,5-х) (0,8+х) = 0 и б) (56,78+у) (24-у) (-у-24) = 0

(-2,5 - x) (0,8 + x) = 0

(-5/2 - x) (4/5 + x) = 0

-5/2 - x = 0

4/5 + х = 0

x₁ = - 5/2

x₂ = - 4/5

(56,78 + y) (24 - y) (-y - 24) = 0

(2839/50 + y) (24-y) (-y-24) = 0

2839/50 + y = 0

24 - y = 0

-y - 24 = 0

y₁ = - 2839/50

y₂ = - 24

y₃ = 24
