Celina says that each of the following expressions is actually a binomial in disguise: (expressions in picture) for example, she sees that the expression in (i) it is algebraically equivalent to − , which is indeed a binomial. (she is happy to write this as + (−), if you prefer.) is she right about the remaining four expressions?
