Question

$6x^{2} - 6 - 5x =$
​

Answer 1

Respuesta:

x1 = 3/2

x2 = -2/3

Explicación paso a paso:

6x^2 - 5x - 6 = 0

a = 6 ; b = -5 ; c = -6

x= (-(-5)±√((-5)^2-4*6*(-6)))/(2*6)

x= (5±√(25+144))/12

x= (5±√169)/12

x= (5±13)/12

x1 = (5+13)/12 = 18/12 ⇒ x1 = 3/2

x2 = (5-13)/12 = -8/12 ⇒ x2 = -2/3
