sqrt5x+21=x+3 square both side.
\n" ); document.write( "5x+21=x^2+6x+9
\n" ); document.write( "x^2+6x-5x+9-21=0
\n" ); document.write( "x^2+x-12=0
\n" ); document.write( "(x+4)(x-3)=0
\n" ); document.write( "x+4=0
\n" ); document.write( "x=-4 ans.
\n" ); document.write( "x-3=0
\n" ); document.write( "x=3 ans.
\n" ); document.write( "----------------------------
