For the equation x - 2 square root of x = 0, solve for all values of x that satisfies the equation.
\n" ); document.write( ":
\n" ); document.write( "\"x+-+2%2Asqrt%28x%29+=+0+\"
\n" ); document.write( "\"x+=+%2B2%2Asqrt%28x%29\"
\n" ); document.write( "Square both sides and you have:
\n" ); document.write( "\"x%5E2+=+4%2Ax\"
\n" ); document.write( "\"x%5E2+-+4x+=+0\"
