a. 2x^2+x-1=0
\n" ); document.write( "discrim=1^2-4*2*-1=9; 2 real zeroes
\n" ); document.write( "---------------
\n" ); document.write( "b. 4/3x^2-2x+3/4=0
\n" ); document.write( "multiply thru by 12 to get:
\n" ); document.write( "16x^2-24x+9=0
\n" ); document.write( "discrim= 24^2-4*16*9=0; 2 identical real zeroes
\n" ); document.write( "--------------
\n" ); document.write( "c. m^2+m+1=0
\n" ); document.write( "discrim=1^2-4*1*1=-3 ; 2 complex zeroes.
\n" ); document.write( "-------------
