Every quadratic equation has two solutions.
If the quadratic expression that's equal to zero is a perfect square,
then the two solutions are equal, and they look like one solution.
Example:
x2 - 6x + 9 = 0
(x - 3)(x - 3) = (x - 3)2 = 0
x = 3
and
x = 3.

How do you know if a quadratic equation will have one two or no solutions How do you find a quadratic equation if you are only given the solution Is it possible to have different quadratic equation?
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
Is it possible for a quadratic equation to have only one solution?
No, it must have two answers.
What is the solution of rational equations reducible to quadratic?
They are the solutions for the reduced quadratic.
How can you have one solution in something that is quadratic?
b^2 - 4ac, the discriminant will tell you that a quadratic equation may have one real solution( discriminant = 0 ) , two real solutions( discriminant > 0 ), or no real solutions( discriminant < 0 ).
Does a quadratic equation has exactly one solution?
Normally it has two solutions but sometimes the solutions can be the same.

If the discriminant of a quadratic equation equals zero what is true of the equation?
It has one real solution.
If the discriminant of an equation is zero then?
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.

Why are there usually two solutions to a quadratic equation?
In the graph of a quadratic equation, the plotted points form a parabola. This parabola usually intersects the X axis at two different points. Those two points are also the two solutions for the quadratic equation. Alternatively: Quadratic equations are formed by multiplying two linear equations together. Each of the linear equations has one solution - multiplying two together means that the solution for either is also a solution for the quadratic equation - hence you get two possible solutions for the quadratic unless both linear equations have exactly the same solution. Example: Two linear equations : x - a = 0 x - b = 0 Multiplied together: (x - a) ( x - b ) = 0 Either a or b is a solution to this quadratic equation. Hence most often you have two solutions but never more than two and always at least one solution.

Does a quadratic function have to have 2 x-values?
If you mean have 2 different real x-value solutions then no.Otherwise a quadratic function will always have 2 solutions, just that they may both be the same value (repeated root) making it seem like there is only one solution value, or non-real (complex) making it seem like it has no solution value.
