20 = 37t - 16t^2

if you are supposed to solve for t: subtract 20 to the other side, then either factor and set both factors equal to zero, or use the quadratic formula on the newly obtained -16t^2 + 37t - 20.
b^2-4ac = 89 is not a perfect square so it is not going to get factored. Quadratic equation is necessary.
