You can put this solution on YOUR website!
$\"16x%5E3-44x%5E2-42x=0\"$ take out a 2x
\n" ); document.write( " $\"2x%288x%5E2-22x-21=0%29\"$ reverse foil
\n" ); document.write( "(2x)(2x-7)(4x + 3)=0 set the stuff in () = 0 and solve(make \"three\" equations)
\n" ); document.write( "2x=0
\n" ); document.write( "x=0
\n" ); document.write( "and
\n" ); document.write( "2x-7=0
\n" ); document.write( "2x=7
\n" ); document.write( "x=7/2
\n" ); document.write( "and
\n" ); document.write( "4x+3=0
\n" ); document.write( "4x=-3
\n" ); document.write( "x=-3/4
\n" ); document.write( "get more then one answer for x
\n" ); document.write( "{-3/4, 0, 7/2}
\n" ); document.write( " \n" ); document.write( "
