Your question is interpreted in following way as it is not clear as cube of what & minus of what?
2x minus x cube plus 5 x minus 2
Solution 1:
= 2 x -1 x cube plus 5 x minus 2
= -2x cube plus 5 x minus 2
= cube of -2 plus 5 x minus 2
= (-8 +5) x -2
= -3 x -2
= 6
Solution2:
=2x-1x cube of +5 x -2
= -2 x 125 x -2
= 500
I think logically the solution 2 must be right. How you interpret the question is important.
