Important:  Please express exponents properly:  -2x^2  Correct
                                                                              -2x2   Not correct

Rewrite  <span>(-2x2 -6x + 7) - (3x3 - 5x + 14)

as

</span><span>- 2x^2 -6x + 7
</span><span>- (3x^3 - 5x + 14)
__________________

Even better, write each power of x in its own column:

</span>- 2x^2 -6x + 7                      - 2x^2 -6x + 7
- 3x^3 + 5x -14         - 3x^3           + 5x -14
---------------------       ------------------------------
                                   -3x^3 - 2X^2 - X - 7       (ANSWER)
