In the first simplification we have returned:

1

--------------------

2 2 2

b t - 2 a b t + a

trying to do a rational function expansion of

1

2 2 2

b t - 2 a b t + a

Using a special rule for expressions of form

M - N

(A + C VAR )

Here we have

[N = 2, A = - a, C = b, M = 1]

# INF

\ I1 - I1 - 2 I1

(D2) > a b (I1 + 1) t
