Find the values of k for each of the following quadratic equations, so that they have two equal roots.(i) `2x^2+k x+3=0` (ii) `k x(x-2)+6=0`

Explanation

To find the values of \( k \) for the given quadratic equations such that they have two equal roots, we will use the condition that the discriminant \( D \) must be equal to 0.

### (i) For the equation \( 2x^2 + kx + 3 = 0 \)

1. **Identify coefficients**:
- Here, \( a = 2 \), \( b = k \), and \( c = 3 \).

2. **Write the discriminant formula**:
