I made a mistake with (c), for that set p(t) = 0.

Solve for t using the quadratic formula

so plug in 24 for t and solve it using the quadratic formula?  So p(24)= -37(24)+1776 (24)-7500 ??

No, that was for question (a)

For question (c), set the equation equal to 0, then use the quadratic formula

You don't need the quadratic formula for a and b, just c

If you know how to use it, then use the formula. Who said anything about discriminant?

p(t) = -37t^2+1776t-7500

a is -37
b is 1776
c is -7500

Put those into the formula
