You can put this solution on YOUR website!
For x - 2√x = 0, we move the root to the other side and then square both sides:
\n" ); document.write( "x = 2√x
\n" ); document.write( "x^2 = 4x
\n" ); document.write( "x^2 - 4x = 0
\n" ); document.write( "x(x - 4) = 0 and
\n" ); document.write( "x = 4 or x = 0
\n" ); document.write( "If we were to graph the two functions, we would find that they intersect at the points (0, 0) and (4, 4).
\n" ); document.write( "
\n" );
