    First u have to factor the expression

    2(9-(x+(x-5))x 8 – 2 x 28 – 2 x 28 – x)

    next you have to remove the parenthesis and multiply

    2(9 -(x + x – 5) x 8 – 2 x 28 – 2 x 28 – x) that’s -2 x 28

    2(9 -( x+ x – 5) x 8 – 56 – 2 x 28 – x)

     2(9 -( x + x -5) x 8 -56 -56 – x)

    Check like terms

    2(9 -(2x-5) x 8 -56 -56 – x)

    multiply by 8

    2(9 – (16x – 40) -56 -56 – x)

    remove parenthesis

    2(9 – 16x + 40 -56 -56 – x)

    calculate  and collect like terms

    2( -63 – 16x – x)

    collect the like terms

    2( -63 -17x)

    your answer is: 2(-63 – 17x)
