Find a polynomial f(x) of degree 3 with real coefficients and the following zeros
1, 3 + 2i
Thank you for the opportunity to help you with your question!
The factor theorem states that a polynomial f(x) has a factor (x − k) if and only if f(k) = 0
zeroes 1, 3-2i (and 3+2i)
f(x) = (x-1)(x-(3-2i))(x-(3+2i)
I need to know what this is when it is multiplied out and simplified with the i's
=x^3-7x^2+19x-13 is final answer .
Pls rate with excelllent rating .
