Extraneous solution

in this video we're going to talk about extraneous solutions if you've never heard the term before I encourage you to review some videos on Khan Academy on extraneous solutions but this is a bit of a refresher it's the idea that you do a bunch of legitimate algebraic operations you get a solution or some solutions at the end but then when you test it in the original equation it doesn't satisfy. So the equation has no solution at all! x = 1 is called an EXTRANEOUS solution, which is really not a solution at all. Example 2: When you multiply through by the LCD and solve the resulting quadratic equation, you get solutions x=2 and x=1. However when we try to check the solution x=2, it causes the first and last denominators to become 0. In mathematics, an extraneous solution (or spurious solution) is a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem. A missing solution is a solution that is a valid solution to the problem, but disappeared during the process of solving the problem. Both are frequently the consequence of performing operations.

This is a necessary step to solving the problem. However, the squaring operation is what creates the extraneous solutions Precalculus Solving Rational Equations Extraneous Solutions. 1 Answer Jim H Mar 8, 2015 Example 1: Raising to an even power Solve #x=root(4)(5x^2-4)#. Raising both sides to the #4^(th)# gives #x^4=5x^2-4#. This requires, #x^4-5x^2+4=0#. Factoring gives #(x^2-1)(x^2-4)=0#. So we need #(x+1. Identifying Special Solutions When you solve an absolute value equation, it is possible for a solution to be extraneous. An extraneous solution is an apparent solution that must be rejected because it does not satisfy the original equation. Identifying Extraneous Solutions Solve ∣ 2x + 12 ∣ = 4x. Check your solutions.

Watch out for extraneous solutions when solving equations with a variable in the denominator of a rational expression , with a variable in the argument of a logarithm , or a variable as the radicand in an nth root when n is an even number Extraneous solutions of radical equations Our mission is to provide a free, world-class education to anyone, anywhere. Khan Academy is a 501(c)(3) nonprofit organization The goal of this task is to examine how extraneous solutions can arise when solving rational equations. The task presents an operation, clearing denominators, which appears to lead to a contradiction. To resolve the contradiction we examine more carefuly what is happening when we clear denominators (MP6) In general, extraneous solutions arise when we perform non-invertible operations on both sides of an equation. (That is, they sometimes arise, but not always.) Non-invertible operations include: raising to an even power (odd powers are invertible), multiplying by zero, and combining sums and differences of logarithms..

3. Algebra Facts Common Types of Mistakes: Extraneous Solutions: Sometimes a method used to solve an equation gives extraneous solutions - values which arise from the solution method but that are not solutions of the original equation. This can happen when a step in the solution process is not strictly reversible, for example, if both sides of an equation are squared at some point
4. In general, extraneous solutions arise when we perform non-invertible operations on both sides of an equation. (That is, they sometimes arise, but not always.) Squaring (or raising to any other even power) is a non-invertible operation. Solving equations involving square roots involves squaring both sides of an equation. Example 1 : To show the idea: The equations: x-1=4 and x=5, have exactly.

We call these extra solutions, extraneous solutions. If it turns out that all of the solutions of a rational equation are extraneous, then the equation would have no solution, meaning, there is no value for the variable that would make the equation a true statement. Let's look at some examples. Example 1: Solve. a. b. c. Solution: a Extraneous solutions Suppose that x is the variable to be solved for in some equation. If we increase the degree of x in the equation (for example, by multiplying through by x − a, clearing the denominator, cross-multiplying, squaring both sides of the equation, etc.) then we run the risk of introducing extraneous solutions.These are false solutions that are created in the algebra process. Extraneous solution are an apparent solutions that do not actually make the original equation true. Consider the equations, x = − 1. For solving the given radical equation use the power rule, raise both sides of equation to the same integer power as root indexthen make use of principle. (x n) n = x.
