1) Solve:
\n" ); document.write( " $\"x-2sqrt%28x%29+=+0\"$ Subtract $\"2sqrt%28x%29\"$ from both sides of the equation.
\n" ); document.write( " $\"x+=+2sqrt%28x%29\"$ Now square both sides.
\n" ); document.write( " $\"x%5E2+=+4x\"$ Divide both sides by x
\n" ); document.write( " $\"x+=+4\"$ \r
\n" ); document.write( "\n" ); document.write( "2) Here's the graph: The red line is y=x. The green line is $\"y=2sqrt%28x%29\"$
\n" ); document.write( "The points of intersection are: (0,0) and (4, 4)
\n" ); document.write( " $\"graph%28300%2C200%2C-5%2C5%2C-5%2C5%2Cx%2C2sqrt%28x%29%29\"$ \n" ); document.write( "

\n" );
