Question

3X²+2x-1=0 meeeeeee aajudemmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Answer 1

∆=(2)²-4.3.(-1)
∆=4+12
∆=16
x= -2+-√16/2.3
x= -2+-4/6

x1=-2+4/6
x1=2/6
x1=1/3

x2=-2-4/6
x2=-6/6
x2= -1

fórmula de Bhaskara ∆= b²-4.a.c
x= -b+-√∆/2.a

no problema a=3, b=2, c= -1
