hours, huh...\r

\n" ); document.write( "\n" ); document.write( "grouping ___ (8x^3 + 4x^2) - (18x + 9) = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factoring ___ 4x^2(2x + 1) - 9(2x + 1) = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rearranging ___ (4x^2 - 9) (2x + 1) = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factoring (difference of squares) ___ (2x + 3) (2x - 3) (2x + 1) = 0\r
