Here, one may notice that the two roots are conjugates of each other. This is not a polynomial, since we are dividing by the variable y. So if you square the Let me write that Now imagine "simplifying" $P (x)$. Approach: Run a loop from 2 to sqrt (n) and check if any number in range (2-sqrt (n)) divides n. import math def check (n): if n == 1: return False for x in range(2, (int) (math.sqrt (n))+1): if n % x == 0: return False return True n = 23 if check (n): print("prime") else: print("not prime") Output: prime 1. first you have 1.41 as the first 3 digits of sqrt 2. Similarly, the root A. They're a little different than the equations you've solved before: they'll require more work for solving, and the problems will be more challenging problems with extraneous solutions. Roots of polynomial are the solution for which the polynomial equation is equal Example 1: Check whether -2 is a root of polynomial 3x3 + 5x2 + 6x + 4. It leads to a contradiction. But it doesn't.
