A polynomial has real coeffients a polynomial with roots b and c and d can be.factored into the form f(x)=a(x-b)(x-c)(x-c) and each of those terms can be raised to any positive power
if it has real coeffients and.one of the roots is a+bi (compex number) then a-bi is also root
ok, so since 2+3i is a root, 2-3i is also a root the function can bex f(x)=a(x-2)(x-1)(x-(2+3i))(x-(2-3i)) where a can be any real number except 0 expand it yourself to get the polynomial because it's hard to type nyubers on mobile note that i=√-1 so i^2=-1
