Well P (x) is the total money they made.

so if P (X) < 0 they had a loss.

so if you plug in 0 you get

0=-7520x^2+15000x

add 7520x^2 to both sides

7520x^2=15000x

(7520x) x is the same thing, if you multiply it out it will still equal 7520x^2

so (7520x) x=15,000x

divide both sides by x and

7520x=15,000

divide both sides by 7520

x=1.995

then you would just need to check a number on both sides,

i. e. 0 and 2

2 gives you a value of - 80 which means anything greater then 1.995 would be negative
