\n" ); document.write( "No; they do not intersect in three points....

\n" ); document.write( "\"2x%5E3=%282-x%29%285x%2B6%29\"
\n" ); document.write( "\"2x%5E3%2B5x%5E2-4x-12=0\"

\n" ); document.write( "The rational roots theorem and synthetic division then show

\n" ); document.write( "\"2x%5E3%2B5x%5E2-4x-12=%282x-3%29%28x%2B2%29%5E2\"

\n" ); document.write( "The graphs intersect at TWO points, with x coordinates -2 and 3/2.
