Question

6x²+x-1=0 conjunto solução

Answer 1

6x^2+x-1=0
delta=b^2-4ac
delta=1^2-4.6.(-1)
delta=1+24
delta=25
x=-b-/+ raiz de delta/2a
x=-1-5/2.6
x=-6/12 (÷6)
x=-1/2
x=-1+5/2.6
x=4/12 (÷4)
x=1/3
S={-1,2 , 1/3}

Answer 2

6x²+x-1=0
Δ=b²-4.a.c
Δ=1²-4.6.(-1)
Δ=1+24
Δ=25
.......................
x=-b±√Δ
2.a
.......................
x=-1±√25
