However, squaring both sides of an equation introduces the possibility of extraneous solutions, so check your answers in the original equation. Solve equations involving cube roots by first isolating the radical and then cubing both sides. how to find a good toothpaste 3/04/2011 · And to find the extraneous roots, you just have to try all the solutions you get, and weed out the ones that don't satisfy the original.

## How To Find Extraneous Roots

4/04/2008 · The roots are 16 and 1, however when one puts them back into the original equation, 1 is found to be extraneous leaving 16 as the only solution. My question is, why do extraneous roots arise? My question is, why do extraneous roots arise?

- 6/06/2012 · In this kind of equation, the source of extraneous roots is multiplication by x, which can introduce an extraneous root if x = 0 turns out to be a root of the new equation, because multiplication by 0 does not produce an equivalent equation. To put it another way, an extraneous root will prove to be extraneous only by making a denominator of the original equation zero. So all you need to do to
- Extraneous Root. more A solution to an equation that SEEMS to be right, but when we check it (by substituting it into the original equation) turns out NOT to be right. 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
- Thus, an essential part of solving any equation with radicals is to check the answers you find, in order to ascertain whether any are extraneous roots. We verify the roots by plugging them into the original equation —- if the number does not solve the original equation, as given in the problem, then it is not a bonafide solution.
- Practice some problems that involve thinking about the conditions for obtaining extraneous solutions while solving radical equations.
