How is it possible to solve this ? Determine values(s) of k for which
1. kx^2 – x – 4 = 0
2. 3x^2 + 5x + k = 0
3. 4x^2 – 3x + k = 0
4. kx^2 + 3x - 7 = 0
5. kx^2 - x - 3 = 0
The problem is not clearly stated.
If complex roots are permitted, any value of can be used.
If the roots must be real, the discriminant must be nonnegative.
If the roots must be rational, the discriminant must be a square.
