\n" ); document.write( " 2x^2+x=-1\r
\n" ); document.write( "\n" ); document.write( " FIRST OF ALL TRY 2 PUT 1 INTO THE LEFT HAND SIDE IN ORDER TO BE FACTORIZED\r
\n" ); document.write( "\n" ); document.write( " 2X^2 +X +1 = 0\r
\n" ); document.write( "\n" ); document.write( " 2X ( X + 1) - 1 (X +1 ) = 0\r
\n" ); document.write( "\n" ); document.write( " (X +1) (2X - 1)\r
\n" ); document.write( "\n" ); document.write( " X + 1= 0 , 2X - 1 = O
\n" ); document.write( " X = -1 , 2X = 1... DIVIDE BOTH SIDES BY 2
\n" ); document.write( " X = - 1 , X = 1/2
\n" ); document.write( "
\n" ); document.write( " X = - 1 OR 1 / 2
\n" ); document.write( "
\n" );
