we are given -4x^2+11x+20 to factor
\n" ); document.write( "first write down all factors of 20
\n" ); document.write( "5,2,2,20,1
\n" ); document.write( "try the following
\n" ); document.write( "4x +5
\n" ); document.write( "-x +4
\n" ); document.write( "we see that we get -4x^2+11x+20
\n" ); document.write( "therefore
\n" ); document.write( "(4x+5)(-x+4) are factors of -4x^2+11x+20
\n" ); document.write( "
\n" ); document.write( "
\n" );
