4-sqrt(4+x^2)=x
\n" ); document.write( "4-x=sqrt(4+x^2)
\n" ); document.write( "square both sides
\n" ); document.write( "16-8x+x^2=4+x^2
\n" ); document.write( "12=8x
\n" ); document.write( "x=3/2 or 1.5
\n" ); document.write( "check
\n" ); document.write( "4-sqrt(6.25)=1.5
\n" ); document.write( "sqrt(6.25)=2.5
\n" ); document.write( "4-2.5=1.5 check
\n" ); document.write( " \n" ); document.write( "
