Question 1172866: A stone is thrown directly upward from a board that is 32 feet high. After t​ seconds, its height above the water is described by the polynomial -16t^2+16t+32.
a. Factor the polynomial completely. Begin by factoring -16 from each term.
b. Evaluate both the original polynomial and its factored form for t=2. Do you get the same answer for each​ evaluation?

a. -16(t^2-t-2)
f(t)=-16(4)+16(2)+32=0
f(t)=-16(4-2-2)=0
Yes
