If - 2 is less than or equal to a and less than or equal to 3, simplify a + 2 + A-3
- 2 less than or equal to a less than or equal to 3
That is - 2
B / (A-2) - B / A is equal to many after simplification
2b/a(a-2)
(A-1) / [a ^ (2 / 3) + A ^ (1 / 3) + 1] is equal to?
Molecular cubic difference
The original formula = [a ^ (1 / 3) - 1] [a ^ (2 / 3) + A ^ (1 / 3) + 1] / [a ^ (2 / 3) + A ^ (1 / 3) + 1]
=a^(1/3)-1
-1 is less than - 2 / A is less than 1
-1
