  2. @Lovy

    You are referring to this question(?)
    (2) Factorise: 8x^2 - xy - 7y^2

    There are 3 terms. Did you notice that the middle term has both "x" and "y"?

    Instead of just a constant, we have 7y^2.
    So, now consider how we can write 7y^2 as a product of 2 factors (y and 7y)?
