Algebra.Com's Answer #464782 by ramkikk66(644)![]() ![]() ![]() You can put this solution on YOUR website! Your solution is right. The quadratic has two roots x = 0 and x = 12.\r \n" ); document.write( "\n" ); document.write( "See the graph below (I have divided the eqn by 25 to make -x^2 + 12*x = 0, which has the same 2 roots, to make it fit.) You are right that the graph opens downwards. It has a max value for x = 6.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( ":)\r \n" ); document.write( "\n" ); document.write( " |
