$\"+sqrt+%28b%29+-+6=+-2%2A+sqrt%28b%29+\"$
\n" ); document.write( "Add $\"+2%2Asqrt%28b%29+\"$ to each side
\n" ); document.write( "then add $\"+6+\"$ to both sides
\n" ); document.write( " $\"+sqrt%28b%29+%2B+2%2Asqrt%28b%29+=+6+\"$
\n" ); document.write( " $\"+3%2Asqrt%28b%29+=+6+\"$
\n" ); document.write( " $\"+sqrt%28b%29+=+2+\"$
\n" ); document.write( "Square both sides
\n" ); document.write( " $\"+b+=+4+\"$
\n" ); document.write( "---------
\n" ); document.write( "check:
\n" ); document.write( " $\"+sqrt+%28b%29+-+6=+-2%2A+sqrt%28b%29+\"$
\n" ); document.write( " $\"+sqrt+%284%29+-+6=+-2%2A+sqrt%284%29+\"$
\n" ); document.write( " $\"+2+-+6+=+-2%2A2+\"$
\n" ); document.write( " $\"+-4+=+-4+\"$
\n" ); document.write( "OK \n" ); document.write( "
