You can choose not to factorise and you'll still end up with the same answer but by doing the converse,the constant (1) helps you to work the 5th term before you multiply the other factor in..Rule of thumb.Expand starting from the constant term first when qn does not say anything about whether the powers should be decreasing or not..
