Extraneous means extra and unnecessary. Extraneous solutions are values that can arise from the process of solving the equation but do not in fact satisfy the initial equation. These solutions occur most often when not all parts of the process of solving are not completely reversible - for example, if both sides of the equation are squared at some point.
It means you performed an operation on the system which was not invertible. This allowed you to come to a solution but that solution is not correct since it is not a proper biconditional relations. That is, you can solve it in terms of p->q but not the reverse (since the inverse operation is not possible).
This usually refers to a word problem. For example, say you have a rectangle with an area of 6 and sides of length (x-3) and (x+2) and you have to find the value of x. Solving said equation, you find that x=-3 or 4. Substituting these values back into the (x-3) and (x+2), you find that if x=-3, one of the sides of the rectangle would equal −6. Since you can't have a distance of -6 (distance is always positive), that answer is considered extraneous. In essence, an extraneous solution is one that does not make sense in the context of the problem.
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
it means no solution. no answer. cant be answered
Yes, empty set means null which is no solution.

What do you mean by "safe"?
It depends on what solution you are talking about. However, generally when we say a solution we mean a homogeneous solution only. but in terms of science it is necessary to specify whether it is homogeneous or heterogeneous.

It depends on what identity you are talking about whether its multiplicative inverse to additive inverse i mean you have to be more specific

I'm assuming you mean the reason George Zimmerman was found not guilty. The short answer is that he was found to have been acting within what the law permitted. The purpose of the jury was to determine whether or not Zimmerman had broken the law, not to determine whether he was ethically or morally sound.

Complexometric titration is a type of volumetric analysis in which the formation of a complex between the analyte and a titrant is used to determine the concentration of the analyte. This method is often used to determine the concentration of metal ions in a sample solution.
what dose solution means
These are tests that are designed to determine whether a substance is acidic (pH less than 7), or basic (pH greater than 7).
its mean solve the problem, to fine the solution like what makes it work.
