3x²-5x-2 = 0
La formula de resolución de ecuaciones cuadráticas es:
x = (-b+-(√b²-4ac))/2a
en este caso:
a =3
b = -5
c = -2
x = (5 +- (√5²-(4*3*-2)))/ 2*3
x = (5+- (√25+24)) / 6
x = (5+- √49) / 6
x = (5+-7) / 6
x₁ = (5 - 7) / 6
x₁ = -2/6 = -1/3
x₂ = (5+7) / 6
x₂ = 12/6 = 2
Son dos los números que satisfacen la condición:
-1/3 2
