Aplica la formula cuadrática:

[tex]\frac{-b\pm\sqrt[]{b^2-4\cdot a\cdot c}}{2\cdot a}[/tex]

Donde:

a = 3

b= -5

c= 1

Reemplazando:

[tex]\frac{-(-5)\pm\sqrt[]{(-5)^2-4\cdot3\cdot1}}{2\cdot3}[/tex][tex]\frac{5\pm\sqrt[]{25-12}}{6}[/tex][tex]\frac{5\pm\sqrt[]{13}}{6}[/tex]

Positivo:

(5+√13) /6 = 1.43

NEgativo:

(5-√13) /6 = 0.23
