Algebra.Com's Answer #136087 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! If x=a, it follows that x^2=ax \n" ); document.write( "Thus x^2 - a^2 =ax - a^2 \n" ); document.write( "or (a+x)(x-a) = a(x-a) \n" ); document.write( "------------------------------------------ \n" ); document.write( "Cancelling the (x-a) is dividing by zero. All that follows is meaningless. \n" ); document.write( "------------------------------------------ \n" ); document.write( "therefore x+a = a \n" ); document.write( "2a = a \n" ); document.write( "2= 1 \n" ); document.write( "Now I know 2 is not = 1.
