WebNov 4, 2016 · 1 Answer. There is some abuse of notation going on. There are regular expressions and there are sets of strings. { 0, 1 } ∗ is the set of all binary strings. This is (rarely) used to mean the regular expression matching all binary strings. ( 0 ∪ 1) ∗ is the regular expression matching all binary strings. ( 0 ∪ 1) + is the regular ...

(1) a 3 − a < 0 --> a ∗ ( a 2 − 1) < 0. Two cases: A. Both multiples are positive: a < 0 and a 2 − 1 > 0, (which means a < − 1 or a > 1 ). As a < 0 then the range would be a < − 1. B. Both multiples are negative: a > 0 and a 2 − 1 < 0, (which means − 1 < a < 1 ). As a > 0 then the range would be 0 < a < 1. greatford crossing
