The discriminant, ( first positive 4 in the constant, then negative 4 as you did not specify this )

b2 - 4ac

------------

(- 7)2 - 4(3)(4)

49 - 48

= 1

============a positive number means two real roots ( - 4 now )

( - 7)2 - 4(3)(- 4)

49 + 48

= 97

============still positive and two real roots
