Algebra.Com's Answer #502927 by Theo(13342)![]() ![]() You can put this solution on YOUR website! if q is the leading coefficient and p is the constant, then the possible rational roots of the polynomial equation are p/q.\r \n" ); document.write( "\n" ); document.write( "your q is 1. \n" ); document.write( "your p is 2\r \n" ); document.write( "\n" ); document.write( "the possible rational roots are +/- 1, 2\r \n" ); document.write( "\n" ); document.write( "3 is not a possible rational root of this equation, therefore false.\r \n" ); document.write( "\n" ); document.write( "while +/- 1 and +/-2 are possible rational roots, neither of them are roots of this equation.\r \n" ); document.write( "\n" ); document.write( "the rational root only lists the possible rational roots, if they exist.\r \n" ); document.write( "\n" ); document.write( "in this case they don't.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a graph of the equation shows that the equation has one root at x = -4.095824 which is not a rational number.\r \n" ); document.write( "\n" ); document.write( "the graph of this equation looks like this:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
