Answer:
3/12-11/12= -8/12
Step-by-step explanation:
any multiple of 12
Since 2, 3 and 4 divide exactly into the number of rocks
We are looking for the common multiples of 2, 3 and 4
2 × 3 × 4 = 24 is possible but dividing by 2 gives 12 the lowest common multiple
Any multiple of 12 gives a possible number of rocks.

Step-by-step explanation:
The given quadratic equation is
The discriminant of this equation is given by;
where a=k, b=20, c=k
For rational solutions, the discriminant must be zero.
Simplify to get:
This implies that:
Take square root to get:
