Algebra.Com's Answer #142087 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! 2 + squareroot(2-x) = x \n" ); document.write( "------------------ \n" ); document.write( "Step 1 - isolate the radical. \n" ); document.write( " \n" ); document.write( "Then square both sides. This eliminates the radical. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "(x-1)*(x-2) = 0 \n" ); document.write( "x = 1 \n" ); document.write( "x = 2 \n" ); document.write( "---------- \n" ); document.write( "2 works. \n" ); document.write( "The 1 is an extraneous solution, ignore it. \n" ); document.write( " |
