How do you identify an unknown solution?
In precipitation, you can add a chemical to a solution and observe what precipitate forms. Acid/base tests will tell you the pH of the substance and whether it is an acid, base or neutral substance. Flame tests are used to identify ions based on the color the flames emit.

What is a real solution?
A real solution in algebra is simply a solution to an equation that is a real number.
What are two real solutions?
It is called the Discriminant, because it can “discriminate” between the possible types of answer: when b2 − 4ac is positive, we get two Real solutions. when it is zero we get just ONE real solution (both answers are the same) when it is negative we get a pair of Complex solutions.

What does find all real solutions mean?
Frequently, in Algebra class, you will be called to find all “real solutions” of an equation. Such questions essentially are asking you to find all solutions of an equation, and should any imaginary solutions (containing the imaginary number ‘i’) come up, to discard these solutions.
Can real solutions be negative?
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A discriminant of zero indicates that the quadratic has a repeated real number solution. A negative discriminant indicates that neither of the solutions are real numbers.
What does no solution mean?
No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. No Solution Equations.
