    Step-by-step explanation:

    (h + k) (x) = x - 2 + 2x + 1

    (h + k) (x) = 3x - 1

    (h + k) (2) = 3 (2) - 1

    (h + k) (2) = 6 - 1

    (h + k) (2) = 5

    Step-by-step explanation:

    (h + k) (x) = [ (x^2 + 1) + (x - 2) ]

    =[ x^2 + x - 1 ]

    then for [ (h + k) (2) ] ... substitute x with 2 and then calculate ...,

    ; (2) ^2 + 2 - 1

    ; 4 + 2 - 1

    (h + k) (2) = 5
