use the discriminant to determine the number of solutions of the quadratic equation, and whether the solutions are real or complex. Note: It is not necessary to find the roots; just determine the number and types of solutions.
\n" ); document.write( "x2 + 6x - 7 = 0
\n" ); document.write( "DEL=6^2-4*1*(-7)=36+28=64..2 SOLUTIONS,REAL\r
\n" ); document.write( "\n" ); document.write( "z2 + z + 1 = 0
