The original equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c930a4a5a684284fd2f26dce4ab0a9a1.png\")
and value of x is 2.
To check the solution of the equation, substitute the value of x=2 in the original equation.

x=2 is not a solution of the original equation.
\
The original equation is and value of x is -2.
To check the solution of the equation, substitute the value of x=-2 in the original equation.
