Find the nature of the roots of the following quadratic equations. If the real roots exist, find them: (i) 2x2 – 3x + 5 = 0 (ii) 3x2 – 4√3x + 4 = 0 (iii) 2x2 – 6x + 3 = 0 2. Find the values of k for each of the following quadratic equations so that they have two equal roots. (i) 2x2 + kx + 3 = 0 (ii) kx (x – 2) + 6 = 0 3.
