You can put this solution on YOUR website!
sqrt(b+1)=sqrt(b+6) -1;
\n" ); document.write( "square both sides
\n" ); document.write( "b+1=b+6-2sqrt(b+6)+1
\n" ); document.write( "collect terms
\n" ); document.write( "-6=-2 sqrt(b+6)
\n" ); document.write( "3=sqrt (b+6)
\n" ); document.write( "square
\n" ); document.write( "9=b+6
\n" ); document.write( "b=3
\n" ); document.write( "-------
\n" ); document.write( "must check to be sure this works
\n" ); document.write( "sqrt(4)=sqrt(9)-1
\n" ); document.write( "2=3-1.
\n" ); document.write( "It does. \n" ); document.write( "

\n" );
