Simplify the following polynomials: (use the ^ symbol to represent exponents) a) (-2x2 -6x + 7) - (3x3 - 5x + 14) b) (2x - 7) (3x + 5) c) (10x2 -3x - 18) ÷ (5x +6)

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)

The answer is 10. sorry i was wrong the 1st time
