is that "T^2" on the first part?

skater4lifez · Answer

or "T Squared"?

skater4lifez · Answer

If so, type in ".25(8^2) - 1.5(8) + 2.5" then subtract the total of "T=5" (so type it in the same way but replace "8" with "5")

Im not positive but I think that is how you get the answer. Check with another to see if I am correct.
