5p^3q \times 3p = 15p^4q\). Expressions with brackets can often be mixed in with other terms. For example, \(3(h + 2) - 4\). In these cases first expand the bracket and then collect any like terms.

That expansion will also come with a change of format. The previous model, with eight qualifying teams, operated as two, four ...
