What is it mean for a possible solution of an equation to be extraneous?

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.

What does extraneous mean What must you do to determine whether a solution is an extraneous solution?
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.
What does it mean when a system of nonlinear equations has an extraneous solution?
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).
What does it mean to be a solution to an equation?
A solution to an equation is a set of values for the variables in the equation which make it true.
What does a solution equation mean?
the set of all values which, when substituted for unknowns, make an equation true.
Why is it no solution when 2x plus 7 equals 1?
Not sure what you mean; that equation certainly has a solution.

What does it mean to be a solution to an equation?
A solution to an equation is a set of values for the variables in the equation which make it true.
What does it mean when an equation has no solution?
It means that the equation has no way of working it out / There is no answer.
What does solution of the equation mean?
its mean solve the problem, to fine the solution like what makes it work.
What does it mean for a value to be a solution to an equation?
For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.
What does a solution equation mean?
the set of all values which, when substituted for unknowns, make an equation true.
What does the math term 'no solution' mean?
There is no real answer to the equation given.
Why is it no solution when 2x plus 7 equals 1?
Not sure what you mean; that equation certainly has a solution.
What does it mean if an equation is simplified to 0 0 do all problems have exactly one solution?
An equation that is simplified to 0 0 is called a perfect equation. It usually have exactly one solution.
What does solution of an equation mean?
It is a set of values for the variable or variables in the equation such that, when those values are put into the equation, the resulting mathematical statement is true. The term can also refer to the process of finding a solution.
What is the solution of this equation x plus 1528?
what the solution to this equation x+15=28 If you mean: x+15 = 28 then the value of x works out as 13
