Gonzalez · Answer 1

We are given the root of a polynomial root 2 + sqrt (3) in which we are asked in the problem to determine the other root of the polynomial. SInce this is an irrational number, then the other root should be the conjugate of that number. Hence the answer to this problem should be 2 - sqrt 3.
