square root of x+6=x?
\n" ); document.write( " $\"sqrt%28x%2B6%29+=+x\"$
\n" ); document.write( "Square both sides:
\n" ); document.write( " $\"x%2B6+=+x%5E2\"$
\n" ); document.write( "x^2-x-6 = 0
\n" ); document.write( "(x-3)(x+2) = 0
\n" ); document.write( "---
\n" ); document.write( "x = 3, x = -2
\n" ); document.write( "---
\n" ); document.write( "Check:
\n" ); document.write( "x = 3
\n" ); document.write( " $\"sqrt%289%29+=+3\"$ Is true
\n" ); document.write( "------------------
\n" ); document.write( "x = -2
