x - $\"sqrt%28x%29\"$ = 0
\n" ); document.write( "implies x = $\"sqrt%28x%29\"$ (by adding $\"sqrt%28x%29\"$ to both sides of the equation)
\n" ); document.write( "-> x^2 = x (square both sides)
\n" ); document.write( "-> x^2 - x = 0
\n" ); document.write( "-> quadratic equation : (-(-1)+- $\"sqrt%28%28-1%29%5E2+-+4%2A1%2A0%29\"$ )/(2*1)
\n" ); document.write( "-> = (1 +- $\"sqrt%281%29\"$ )/2 = (1 +- 1)/2 = 0/2 or 2/2 = 0 or 1\r
\n" ); document.write( "\n" ); document.write( "now when graphing simply use intersection pts (0,0) and (1,1)
\n" ); document.write( "y=x is straight line with slope 1
\n" ); document.write( "as for the other, just pick a few points then draw the curve
\n" ); document.write( "(1/2, $\"%281%2F2%29%5E2\"$ )=(1/2, $\"sqrt%282%29\"$ /2) is another good pt to start with \n" ); document.write( "

\n" );
