Question

qual valor de 6x2-13x+6=0

Answer 1

6x^2-13x+6=0
delta=b^2-4ac
delta=(-13)^2-4.6.6
delta=169-144
delta=25
x=-b-/+ raiz de delta/2a
x=-(-13)-5/2.6
x=13-5/12
x=8/12 (:4)
x=2/3
x=-(-13)+6/2.6
x=13+6/12
x=19/12

Answer 2

6x2-13x+6=0

Δ=b2-4ac

Δ=13^2-4.6.6

Δ=169-144

Δ=25

x=-b+- √Δ /2a

x1=13+5/12= 18/12=3/2

x2=13-5/12= 8/12=2/3
