$\"sqrt%28x+%2B+3%29+=+2%2Asqrt%28x%29\"$
\n" ); document.write( "square both sides
\n" ); document.write( " $\"x+%2B+3+=+4x\"$
\n" ); document.write( "subtract $\"x\"$ from both sides
\n" ); document.write( " $\"3x+=+3\"$
\n" ); document.write( " $\"x+=+1\"$
\n" ); document.write( "check:
\n" ); document.write( " $\"sqrt%28x+%2B+3%29+=+2%2Asqrt%28x%29\"$
\n" ); document.write( " $\"sqrt%281%2B+3%29+=+2%2Asqrt%281%29\"$
\n" ); document.write( " $\"2+=+2\"$
