Algebra.Com's Answer #597337 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! Not clear how much latitude I am allowed.\r \n" ); document.write( "\n" ); document.write( "This has no more than two roots, and if they aren't complex, they must be greater than 0, because the factors to multiply to a positive number but add to a negative number. Therefore the factors must be (x- ) and (x- ). The intercept is positive 12, so it is a parabola with a vertex below the y-axis and two positive rational roots. \n" ); document.write( " |
