Answer:
5375 should be it
Step-by-step explanation:

54÷2 since there 2 girls for each boy so 2 girls for 1 boy and there 54 girls
54÷2=27
so there 27 boys in the league
To factor, you split the equation so the factors multiply to get the whole equation.
(x-2)(x+2)
Then, interpret the factors.
The zeros can be found at (2,0) and (-2,0).
x=2, x=-2
