Reorder in standard form: ax^2 + bx + c
-n^2 + 2n + 0
2x-x^3 ;
The expression for 'Twice a number decreased by the cube of the same number' can be represented as 2 x − x 3 . Here, 2 x is twice the number and − x 3 indicates a decrease due to the cube of that number. This provides a clear algebraic representation of the problem at hand.
