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)
