Answer:
the "negative solution" is -3
Step-by-step explanation:
Represent the number by n.
Then n^2 - 24 = 5n
We rewrite this in standard quadratic form:
n^2 - 5n - 24 = 0
This factors as follows; (n + 3)(n - 8) = 0
The roots are n = -3 and n = 8. Thus, the "negative solution" is -3
Let q represent the number of quarters. Then 20-q is the number of dimes. The money total is
... 25q +10(20-q) = 335
... 15q +200 = 335
... 15q = 135
... q = 135/15 = 9
The person has 9 quarters.
