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
