 Question 71858: Here is another one that is not explained in the 8 books that I have. At least not good enough whereas I can make sense of it. the degree three polynomial f(x) with real coefficients and leading coefficient 1, has 4 and 3 + i among its roots. Express f(x) as a product of linear and quadratic polynomials with real coefficients. Possible answers: f(x) =(x+4)(x^2 + 6x +10) f(x) =(x-4)(x^2 -6x -9) f(x) =(x-4)(x^2 -6x +10) f(x) = (x-4)(x^2 -6x +9) Thanks to anyone who can possibly explain this to me.
