Answer 1

Answer:

Given, f(x) = x4 + 4x2 + 6

              = (x2)2 + 4x2 + 6

Put x2 = a

Hence x4 + 4x2 + 6 = (x2)2 + 4x2 + 6

                            = a2 + 4a + 6

To find the zero of the above polynomial, we take a2 + 4a + 6 = 0

The above equation does not have a real root

Hence there is no zero for this given polynomial.
