A solution of a simplified version of an equation that does not satisfy the original equation. 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.

I think it is an answer that you have gotten by solving, but doesn't work when you plug it in the original equation.

Could anyone give a better/correct answer?
