Steve HuttonFebruary 23, 2017 at 11:09 amWhen you expand the brackets and group like terms, the expression arrived at is -2ab-2b^2. This is an alternative form of the original expression which, when factorised comes to -2b(a+b), the answer we were looking for. The answer confused me as well. It also confused Stuart, as he had to do the working twice over to get it right.
