f(x) = -5x^2 - x + 20;

f(3) = -5*3^2 - 3 + 20 = -5*9 - 3 + 20 = -45 - 3 + 20 = -28;

Because
\frac{f(x)}{x-3} = 2x^{2} + 10x - 1
therefore
f(x) = (x-3)(2x² + 10x - 1) + k, where k =  constant.

Because f(3) = 4, therefore k =4.
The polynomial is
f(x) = 2x³ + 10x² - x - 6x² - 30x + 3 + 4
      = 2x³ + 4x² - 31x + 7

Answer:  f(x) = 2x³ + 4x² - 31x + 7

7:45 -1 hour=6:45

The concert started at 6:45


7:45+2 hours=9:45

The concert will be over at 9:45

The time outside the theater is

5:30a.m. or 5:30p.m.

It's most likely 5:30p.m. as 5:30a.m. is really early in the morning.
