Question

Valor de x
b)6x²+5x+1=0

Answer 1

a= 6  b= 5  c = 1

delta = b2 - 4ac

delta = (5)2 - 4.6.1

delta = 25 - 24

delta = 1

x = - b + - V delta / 2.a

x= - 5 + - V1  / 2.6

x1= - 5 - 1 / 12

x1 = - 6 /12

x1 = - 1 / 2

x2 = - 5 + 1 / 12

x2 = - 4 / 12

x2 = - 1 / 3

S = { - 1 / 3 , - 1 / 2 )
