Algebra.Com's Answer #23012 by fractalier(6550)![]() ![]() 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( " |
