\n" ); document.write( " $\"sqrt%28x%29%2B2=sqrt%28x-1%29\"$
\n" ); document.write( "Square both sides.
\n" ); document.write( " $\"x%2B4%2Asqrt%28x%29%2B4=x-1\"$
\n" ); document.write( " $\"4%2Asqrt%28x%29%2B4=-1\"$
\n" ); document.write( " $\"4%2Asqrt%28x%29=-5\"$
\n" ); document.write( " $\"sqrt%28x%29=-%285%2F4%29\"$
\n" ); document.write( " $\"x=25%2F16\"$
\n" ); document.write( "Check the solution,
\n" ); document.write( " $\"sqrt%2825%2F16%29%2B2=sqrt%2825%2F16-1%29\"$
\n" ); document.write( " $\"2+%2B-+5%2F4+=+0+%2B-+sqrt%289%2F16%29\"$
\n" ); document.write( " $\"2+%2B-+5%2F4+=+0+%2B-+3%2F4\"$
\n" ); document.write( "The statement is true because
\n" ); document.write( " $\"2-5%2F4=3%2F4\"$ \n" ); document.write( "
