Which expression represents the sum of the following?
5 / 2t + 1 + 1 / 4t^2 + 4t + 1
a)10t + 4 / (2t + 1)^2
b) 4 / (2t + 1)^3
c)10t + 1 / (2t + 1)^2
d) 4 / 4t^2 + 6t + 2

You have to use parenthesis on these. If you do not see the problem you have created by typing these without parenthesis, you need a tutor.
