Can square root equations have extraneous solutions?
Can square root equations have extraneous solutions?
When you square a radical equation you sometimes get a solution to the squared equation that is not a solution to the original equation. Such an equation is called an extraneous solution. Remember to always check your solutions in the original equation to discard the extraneous solutions.

Why do square root equations have extraneous solutions?
Extraneous Solutions occur because squaring both sides of a square root equation results in 2 solutions (the positive and negative number). Therefore, one of those numbers will be an extraneous solution, or an extra solution which does not fulfill the original equation.
How do you determine if the given roots is an extraneous roots?
Example: you work on an equation and come up with two roots (where it equals zero): “a” and “b”. When you put “a” into the original equation it becomes zero, but when you put in “b” it doesn’t. So “b” is an extraneous root. This often happens when we square both sides during our solution.
How do you know if a solution is extraneous?
To determine if a solution is extraneous, we simply plug the solution into the original equation. If it makes a true statement, then it is not an…
How do you get extraneous solutions?
To find whether your solutions are extraneous or not, you need to plug each of them back in to your given equation and see if they work.
What is extraneous root in math?
An “extraneous root” may be defined as “a value obtained. for an unknown in the solution of an equation which is not a. root of the equation.” It may be noted first that authors of.
How do you write extraneous solutions?
An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x , 1x − 2+1x + 2=4(x − 2)(x + 2) .
How do you identify extraneous solutions?
To find whether your solutions are extraneous or not, you need to plug each of them back in to your given equation and see if they work. It’s a very annoying process sometimes, but if employed properly can save you much grief on tests or quizzes.
What is extraneous root solution?
How do you know if a solution is extraneous or extraneous?
What is extraneous root?
An “extraneous root” may be defined as “a value obtained. for an unknown in the solution of an equation which is not a. root of the equation.” It may be noted first that authors of. textbooks usually fail to give a definition of extraneous roots ; second, that the definition given above is faulty, in that it leaves.
