Step one: (((x2)+x)+1)+((0-(2x23•x))+5)

Step two: Check for a perfect cube. 2.1 -2x24+x2+x+6 is not a perfect cube.

2.2 Factoring: -2x24+x2+x+6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: x+6

Group 2: -2x24+x2

Pull out from each group separately :

Group 1: (x+6) • (1)

Group 2: (2x22-1) • (-x2)

The groups have no common factor and can not be added up to form a multiplication.

So the answer would be, -2 (x24) + (x2) ++ 6.
