What is the difference(4x^3-3x^3+2x^2-7)-(x^4+2 x^3-4x-3)

- - x³ + 2x² + 4x - 4

Step-by-step explanation:

This is a problem that involves combining like terms

1. Original equation

(4x³ - 3x³ + 2x² - 7) - ( + 2x³ - 4x - 3)

2. Remove parentheses, remember to change each of the signs from the second grouping as we are subtracting

4x³ - 3x³ + 2x² - 7 - - 2x³ + 4x + 3

3. Rearrange so that the terms are grouped by the powers of x

- + 4x³ - 3x³ -2x³ + 2x² + 4x -7 + 3

4. Combine like terms based on the powers of x

- - x³ + 2x² + 4x - 4
