There are two complex solutions.
The discriminant must be a perfect square or a square of a rational number.
It discriminates between the conditions in which a quadratic equation has 0, 1 or 2 real roots.
In that case, the discriminant is not a perfect square.
it has one real solution
There are two complex solutions.
It has one real solution.
The discriminant must be a perfect square or a square of a rational number.
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). That is true only for elementary mathematics. In more advanced mathematics (complex analysis), the quadratic equation can be used in all cases except when a = 0: the value of the discriminant is irrelevant.a = 0.

It discriminates between the conditions in which a quadratic equation has 0, 1 or 2 real roots.
It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots
In that case, the discriminant is not a perfect square.
The equation must be written in the form ( ax^2 + bx + c = 0 ), where ( a \neq 0 ). This is the standard form of a quadratic equation. If the equation is not in this form, you may need to rearrange it before applying the quadratic formula.
True
C
it has one real solution
That its roots (solutions) are coincident.
