square root function non-negative

Since square root of a negative number is not real, we define a function f : R + R such that ..

Nature of the roots - Without solving the quadratic equation, the nature of the roots can be determined using the discriminant. i) D >0 i.e., positive and not a perfect square. The roots are real and distinct (irrational). ii) D >0 i.e., perfect sq..
