sqrt (6x+2) = x+1
\n" ); document.write( "square both sides
\n" ); document.write( "6x+2= (x+1) sqrd
\n" ); document.write( "6x+2=x sqrd + 2x + 1
\n" ); document.write( "-x sqrd + 6x-2x+2-1=0
\n" ); document.write( "-x sqrd + 4x + 1=0
\n" ); document.write( "or x sqrd - 4x -1=0
\n" ); document.write( "using quadratic formula
\n" ); document.write( "a=1, b=-4, c= -1
\n" ); document.write( "-b+/- sqrt -b sqrd-4ac/2a
\n" ); document.write( "-(-4)+/- sqrt -(-4)sqrd - 4(1)(-1)/2(1)
\n" ); document.write( "4+/- sqrt 16+4/2
\n" ); document.write( "4+/-sqrt20/2
\n" ); document.write( "4/- sqrt (4*5)/2
\n" ); document.write( "4+/-2sqrt 5/2
\n" ); document.write( "x1=2+srt 5
\n" ); document.write( "x2=2-sqrt 5
\n" ); document.write( " \n" ); document.write( "
\n" );
