You can put this solution on YOUR website!
$\"x-sqrt%28x%29=0\"$ Add $\"sqrt%28x%29\"$ to both sides
\n" ); document.write( " $\"x%5E2=%28sqrt%28x%29%29%5E2\"$ }Square both sides
\n" ); document.write( " $\"x%5E2=x\"$ Subtract from sides
\n" ); document.write( " $\"x%5E2-x=0\"$
\n" ); document.write( " $\"x%28x-1%29=0\"$ Factor out an x
\n" ); document.write( " $\"x=0\"$ One solution
\n" ); document.write( " $\"x-1=0\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( "The graph of $\"x-sqrt%28x%29=0\"$ represents the x intercepts. In a sense, y=0 which allows you to find the x-intercepts.
\n" ); document.write( " $\"graph%28+300%2C+200%2C+-5%2C+5%2C+-2%2C+2%2C+x-sqrt%28x%29%29\"$ Notice the x-intercepts at x=0 and x=1 (it may be hard to see the x=0 solution)
\n" ); document.write( "Hope this helps. \n" ); document.write( "
