why cant you leave the answer as it is in step 2
(r^3 - 1)(9t^2 - 4)
Answer provided by our tutors
When selecting 'Factor' the web-solver will factor the expression:
That is, it will find all the factors.

9t^2 - 4 = (3t)^2 - 2^2 = (3t - 2)(3t + 2)
the factors are (r - 1), (r^2 + r + 1), (3t - 2) and (3t + 2).
That is why the final results is:
