Question

1+2i multiplicity 2
does anyone know the additional zeros
is it 1-2i multiplicity 2 or just 1-2i

Answer 1

1+2i multiplicity 2 means
2(1+2i)
mm what is ur Qn exactly ?

Answer 2

what the zeros are

Answer 3

zeros of what ? :D

Answer 4

1+2i multiplicity 2

Answer 5

well 2(1+2i)=2+4i
PS :- 1+2i is a complex number and i is not a variable \(i=\sqrt-1\)

Answer 6

A polynomial with real coefficients that has complex roots has complex roots in complex conjugate pairs.

If your polynomial has roots 1 + 2i multiplicity 2,
that means it has the root 1 + 2i and 1 + 2i (the same root twice).

Each of these two equal roots must come as a pair of complex conjugate roots, so there must also be the roots 1 - 2i and 1 - 2i, or 1 - 2i multiplicity 2.

Answer 7

mmm is that was her Qn !!
lolz like a buzzle
