A, b, and c are polynomials, where a = n, b = 2n + 6, and c = n2 – 1. what is ab – c in simplest form?

a=–n2 + 3n + 5
b=n2 + 6n + 1
c=2n2 + 6n – 1
d=3n2 + 5

Adepartment store purchases screen-printed t-shirts at a cost of $5 per shirt. they mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.
