polynomial, degree and zeros: degree 4, zeroes 2-3i, -1(x2)

[nae33]

form a polynomial f(x) with real coefficients having the given degree and zeros
degree: 4
zeros: 2-3i, -1 (multiplicity 2)

multiply it out

Re: polynomial, degree and zeros (help)

-1?

x-(-1) = (x+1)

Multiplicity 2?

(x+1)^2

2-3i?

x-(2-3i)

Real Coefficients

x-(2+3i)

That's it.
