Algebra.Com's Answer #574654 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Calculate the discriminant to determine the number of real roots. \n" ); document.write( "y = x2 + 3x + 9 \n" ); document.write( "D = b^2-4ac \n" ); document.write( "D = 3^2 - 4*1*9 = 9-36 = -27 \n" ); document.write( "----- \n" ); document.write( "Since D is negative the equation has no Real roots \n" ); document.write( "------------------------------------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------- \n" ); document.write( "How many real roots does the equation have? \n" ); document.write( "one real root \n" ); document.write( " two real roots \n" ); document.write( " no real roots \n" ); document.write( " no solution to the equation \n" ); document.write( " |
