    Can someone explain how to do Q4Bii as the MS makes no sense.

    Consider the expansion of  (\alpha + \beta + \gamma )( \alpha \beta + \beta \gamma + \gamma \alpha ) and compare it with th expansion of the product given in the question.
    What you have to do with these questions is find a way of multiplying expressions with known values to make get a similar expression to the one given. Similar to what you do when you have to find  \alpha^2 + \beta^2 + \gamma^2 or when you have to find  \alpha^3 + \beta^3 with quadratics.
