Which of the following is equivalent to the expression (t2 − t − 6)(t − 3)−1 ?
a. t3 − 9t +18
b. (t − 2)(t + 3)
c. (t + 2)(t − 3)
d. (t − 2)
e. (t + 2)this is the answer how is the problem worked out?

If t +2 is the answer, you have typed the question wrong. It should be
(t^2 − t − 6)*(t − 3)^1
You omitted the ^ for the exponents. The t3 can be cancelled out after factoring (t^2 − t − 6).

Which of the following ia equivalent to the expression (t^2t6)(t3)^1?
a. t^39t+18
b. (t2)(t+3)
c. (t+2)(t3)
d. (t2)
e. (t+2)
The correct answer is e, however, I cannot figure out how to work the problem out to get that answer. Can you show me how to work this out correctly?
