1. Find the value of k for kx2 + 2x - 1 = 0, so that it has two equal roots

2. Find the value of k for k x2 - 2√ 5 x + 4 = 0, so that it has two equal roots.

3. If the roots of the equation (b - c) x2 + (c - c) x + (a - b) = 0 are equal, accordingly prove that 2b = a + c.

4. Find the discriminant of the quadratic equation 3x2– 4 √3 x + 4 = 0, and hence find the nature of its roots.

5. Find the value of k for 2 x2 + k x + 3 = 0, so that it has two equal roots.

6. Find the value of k for k x (x – 2) + 6 = 0, so that it has two equal roots.

7. Find the value of k for which the equation x2 + 5kx + 16 = 0 has no real roots.

8 Find the discriminant of the quadratic equation 2x2– 6x + 3 = 0, and hence find the nature of its roots.

9. Find the value of k for k2 x2 – 2 (2 k - 1) x + 4 = 0, so that it has two equal roots.

10. Find the value of k for (k + 1) x2 – 2 ( k - 1) x + 1= 0, so that it has two equal roots.
