Explanation / Answer

             Use   the    Rational   Theorem   of zeroes to    find    the   real zeroes of the polynomial

             function

             Given   function   is  

                 f(x) = 4x^4 + 9x^3 + 14x^2 + 27x + 6

            Since ,

                f(-2) = 0

           Therefore , (x+2)    is     a factor    of    f(x)

            We   Can   find   rest    of    the factors   as

               [ 4x^4 + 9x^3 + 14x^2 + 27x + 6 ] / [ x + 2]

             = (4x+1)( x^2 + 3)

            Therefore , All    the   factors    are

            = (4x + 1)( x^2 + 3)( x + 2)

   So , All zeroes are

x = - 1/4 , x = -2    and    x = (sqrt3)i

   Now, All    real zeroes are

x = -1/4 ,    x = -2

   and    All the real zeroes to factor    F is

            =    [ 4x^4 + 9x^3 + 14x^2 + 27x + 6 ]

=    (4x + 1)(x^2 + 3)( x + 2)
