${x}^{2} + 5x + 4 = 0$

Answer 1

X² + 5X + 4 = 0

SEA : A = 1
SEA B : = 5
SEA C : = 4

APLICAMOS LA FÓRMULA:
x = - b +- √(b² - 4ac)/2a
x₁ = - 5 + √(5² - 4 (1) (4))/2 (1)
x₁ =  - 5 + √(25 - 16)/2
x₁ = - 5 + √(9)/2
x₁ = (- 5 + 3)/2
x₁ = - 2/2
x₁ = - 1


PARA X₂
x₂ = (- 5 - 3)/2
x₂ = - 8/2
x₂ = - 4

Respuesta.
x₁ = - 1
x₂ = - 4
