Q2. Find the values of k for each of the following quadratic equations, so that they have two equal roots.
For two equal roots for the quadratic equation:
The value of the discriminant .
Can be written as:
Comparing and getting the values of a,b, and, c.
The value of
But is NOT possible because it will not satisfy the given equation.
Hence the only value of is 6 to get two equal roots.
