WebbAccording to the (a+b) (a-b) formula, the a plus b times a minus b is equal to a squared minus b squared. ( a + b) ( a − b) = a 2 − b 2. In this algebraic identity, a and b are two literals and they are used as variables to represent the terms. The two variables a and b form binomials a + b and a − b by the summation and subtraction ... WebbIf A and B are sets, then A × B = B × A. You can see that A × B = B × A cannot be a set identity by counter-example. Suppose A = {1} and B = {2}. Then A × B = { (1,2) } while A × B = { (2,1) }. If A and B are sets, A = 10 and B = 5, then A × B = ? 50 Correct Answers 50.0 (with margin: 0.0) True or false? {∅} is the empty set. True False can sesonalallergied cause sore tired eyes
