$\"sqrt%28x%2B2%29-x=0\"$
\n" ); document.write( ":
\n" ); document.write( " $\"sqrt%28x%2B2%29=x\"$ added x to both sides
\n" ); document.write( ":
\n" ); document.write( " $\"x%2B2=x%5E2\"$ squared both sides
\n" ); document.write( ":
\n" ); document.write( " $\"x%5E2-x-2=0\"$ put all terms on 1 side
\n" ); document.write( ":
\n" ); document.write( " $\"%28x-2%29%28x%2B1%29=0\"$ factored
\n" ); document.write( ":
\n" ); document.write( "x=2 and x=-1
\n" ); document.write( ":
\n" ); document.write( "check for extraneous roots
\n" ); document.write( ":
\n" ); document.write( "-1 is and extraneous root so we throw it out(it does not make the statement true
