    The attempt at a solution

    Multiply out the brackets giving

    p² + q² +2pq + 5p + 5q

    now how do I factorise that?

    Both terms in the original problem have a common factor. Factor it out.

    If something is already factored for you (like (p+q)2 try not to multiply it again!

    so i need to factorise the factorised. Hmmm. Well p + q is in each bracket so ill put that on the outside

    [tex]p + q(5 + p + q)[/tex]

    is that right?

    There is one set of parentheses standing between you and a correct answer.

    [tex](p + q)(5 + p + q)[/tex]
