IF THE EQUATION IS 2X^2-5X=3
\n" ); document.write( "THEN
\n" ); document.write( "2X^2-5X-3=0
\n" ); document.write( "(2X+1)(X-3)=0
\n" ); document.write( "2X+1=0
\n" ); document.write( "2X=-1
\n" ); document.write( "X=-1/2
\n" ); document.write( "&
\n" ); document.write( "X-3=0
\n" ); document.write( "X=3
\n" ); document.write( "PROOF
\n" ); document.write( "2(-1/2)^2-5*(-1/2)=3
\n" ); document.write( "2(1/4)+5/2=3
\n" ); document.write( "1/2+5/2=3
\n" ); document.write( "6/2=3
\n" ); document.write( "3=3
\n" ); document.write( "AND
\n" ); document.write( "2*3^2-5*3=3
\n" ); document.write( "2*9-15=3
\n" ); document.write( "18-15=3
\n" ); document.write( "3=3\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
