Question

Simplify the following polynomials: (Use the ^ symbol to represent exponents)

Answer 1

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

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

as

- 2x^2 -6x + 7
- (3x^3 - 5x + 14)

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

- 2x^2 -6x + 7                      - 2x^2 -6x + 7
- 3x^3 + 5x -14         - 3x^3           + 5x -14

                                   -3x^3 - 2X^2 - X - 7       (ANSWER)
