Question

Find remaining zereos of f

Answer 1

the function is:

degree: 4

and we know that some zeros are:

`x=7i,3,-3`

because the function is degree 4 we know that it should have 4 zeros. we also know that the function is symetric because of the real solutions, so the las solution will be the negative of the imaginari root so the remaining zeros are:

`x=-7i`
