Answer:
350p2+19500p-199000
(The first term is actually -350p² but I guess you have to write it as -350p2)
Explanation:
Looks like that first term in the revenue equation is -350p²
We have
E = -1500p + 199000
R = -350p² + 18000p
Profit = Revenue - Expenses = R - P
Profit = -350p² + 18000p - (-1500p + 199000)
= 350p² + 18000p + 1500p - 199000
= 350p² + 19500p - 199000
