For this case we must indicate which of the equations shown can be solved using the quadratic formula.
By definition, the quadratic formula is applied to equations of the second degree, of the form:

Option A:

Rewriting we have:

This equation can be solved using the quadratic formula
Option B:

Rewriting we have:

It can not be solved with the quadratic formula.
Option C:

Rewriting we have:

This equation can be solved using the quadratic formula
Option D:

Rewriting we have:

It can not be solved with the quadratic formula.
Answer:
A and C
A) 60 Clown fish / 5 = 12
12 x 4 = 28 Angel fish
B) 28 Angel fish / 4 = 12
12 x 3 = 36 Gold fish
C) Add all fish 28 Angel fish + 36 Gold fish + 60 Clown fish = 124 Fish in total
