Question

A polynomial function P(x) with rational coefficients has the given roots. Find two additional roots of P(x)= 0, 7- 5 squared and -2i

Answer 1

2 & +2i

Explanation:

The two additional roots of the polynomial functions are:

1. 7-5 = 2

2. Irrational root of a polynomial functions are always in pairs, hence

- 2i will have +2i as its pair
