Recently I asked a doubt to experts regarding difficulty in finding the sum and the product for large numbers , One expert said that we can use quadratic formula but then finding the discriminant (finding square root) will also take more time right? Factorization is easy but finding factors for large numbers is also difficult and time consuming . So please help and solve this matter as fast as possible , Maths board on Wednesday :(
