Answer:
6x^4 + 3x³ + 4x² + 2
Step-by-step explanation:
When adding, combine terms with the same amount of variables. Combine like terms.
6x^4 + 3x³ - 1 + 4x² - 3x + 3
Reorder from greatest power to least
6x^4 + 3x³ + 4x² - 3x + 3 - 1
Simplify. Combine like terms
6x^4 + 3x³ + 4x² - 3x + (3 - 1)
6x^4 + 3x³ + 4x² + 2
6x^4 + 3x³ + 4x² + 2 is your answer
