(x + 1)(2x^2 + 3x - 1) : Can be solved in multiple ways but easiest for me :P
x (2x^2 + 3x - 1) + 1(2x^2 + 3x - 1)
(2x^3 + 3x^2 - x) + (2x^2 + 3x - 1)
2x^3 + 5x^2 + 2x - 1
When the corner is cut to a dimension of x, then the flap folded up, its height will be x. The appropriate choice is the last one, ...
