Answer 1

x² + x = 0

Factor común: x

x (x + 1) = 0

x₁ = x = 0

x₁ = 0

x₂ = x +1 = 0

x₂ = x = -1

x₂ = -1

y² - 12y = 0

Factor común: y

y (y -12) = 0

y₁= y = 0

y₁= 0

y₂= y -12 = 0

y₂= y = 12

y₂= 12

3a² - 4a = 0

Factor común: a

a (3a - 4) = 0

a₁ = a = 0

a₁ = 0

a₂ = 3a - 4 = 0

a₂ = 3a = 4

a₂ = a = 4 / 3

a₂ = 4 / 3

4x² + 2x = 0

Factor común: 2x

2x (2x + 1) = 0

x₁= 2x = 0

x₁= x = 0 / 2

x₁= x = 0

x₁= 0

x₂ = 2x +1 = 0

x₂ = 2x = -1

x₂ = x = - 1 / 2

x₂ = - 1 / 2
