    Immediately you can get 2a(b-2c)+d(b-2e).

    If you have a typo (e should be c?), then you have (2a+d)(b-2c).

    the question asks

    Factorise the following expressions by extraction or grouping of the common factors

    2ab - 4ac + bd - 2de

    Then the best you can do is, as mathman said, 2a(b- 2c)+ d(b- 2e).
