It has one real solution.
a = 0. That is because a = 0 implies that there is no quadratic term and so the equation is not a quadratic!There may be some who make claims depending on the value of the discriminant (which is b2-4ac).

The equation has two real solutions.
The two solutions are coincident.
True Yes. Although the term 'quad' stands for four, a quadratic equation is a polynomial of second degree.
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
If the discriminant of a quadratic equation is less than zero, it indicates that the equation has no real solutions. Instead, it has two complex (or imaginary) solutions that are conjugates of each other. This means the parabola represented by the quadratic equation does not intersect the x-axis.

It discriminates between the conditions in which a quadratic equation has 0, 1 or 2 real roots.
The discriminant must be a perfect square or a square of a rational number.
That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.
In that case, the discriminant is not a perfect square.
If the discriminant of a quadratic equation is positive, it indicates that the equation has two distinct real roots. This means that the graph of the equation intersects the x-axis at two points. A positive discriminant also suggests that the solutions are not repeated and that the parabola opens either upward or downward, depending on the leading coefficient.
If the discriminant of a quadratic equation is zero, it indicates that the equation has exactly one real solution, also known as a double root. This means the parabola represented by the quadratic touches the x-axis at a single point rather than crossing it. In other words, the vertex of the parabola lies on the x-axis.
There are two complex solutions.
That its roots (solutions) are coincident.
That its roots (solutions) are coincident.
