Respuesta :
This has non-real roots.
The discriminant is given by b²-4ac. If this is equal to 0, there is 1 real solution; if it is a positive number, there are 2 real solutions; and if it is negative, there are no real solutions.
In our equation, a = 1, b = -5, and c = 7:
(-5)²-4(1)(7) = 25 - 28 = -3
Thus no real solutions.
