You can put this solution on YOUR website! Form a polynomial f(x) with real coefficients having the given degree and zeros.
Degree 4 zeros: -2+2i & 1 multiplicity 2
-----
If f has Real coeffficient -2-2i must also be a zero
--------
f(x) = (x-(-2+2i))(x-(-2-2i))(x-1)^2
---------------------------
f(x) = ((x+2)-2i)((x+2)+2i)(x-1)^2
------
f(x) = ((x+2)^2+4))(x^2-2x+1)
----
f(x) = (x^2+4x+8)(x^2-2x+1)
----
multiply each term of x^2+4x+8 by (x^2-2x+1)
