Algebra.Com's Answer #149589 by actuary(112)![]() ![]() ![]() You can put this solution on YOUR website! A quadratic equation may have 0,1,or 2 REAL solutions. REAL solutions refers to real numbers as compared to COMPLEX numbers.\r \n" ); document.write( "\n" ); document.write( "To determine the number of REAL solutions, you need to calculate the amount under the radical arising from the application of the quadratic formula, i,e b^2-4ac.\r \n" ); document.write( "\n" ); document.write( "b^2-4ac is called the determinant. If the determinant = 0, the quadratic equation has one REAL solution. If the determinant > 0, the quadratic equation has 2 REAL solutions. If the determinant < 0, there are 0 REAL solutions.\r \n" ); document.write( "\n" ); document.write( "Larry\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
