Question

cual es la solución. De :5x^2+3x=2

Answer 1

5x^2+3x-2=0

5x^2+3x-10
(5x+5) (5x-2)/5
5(x+1) (5x-2)/5
(x+1) (5x-2)
x=-1. x=2/5

Answer 2

Respuesta:

5x² + 3x = 2
5x² + 3x - 2 = 0
5x          - 2
  x         + 1 

(5x - 2)(x + 1) = 0

5x - 2 = 0
5x = 2
x = 2 / 5

x + 1 = 0
x = - 1

x₁ = 2 / 5
x₂ = - 1
