Answer:
8x³ - 3x² - 4x + 3
Step-by-step explanation:
first, eliminate the parenthesis. you can just drop the first set, but you have to distribute the negative through the second set.
9x³ - 4x + 2 - x³ - 3x² +1
then combine like terms (terms with the same exponent)
8x³ - 4x + 3 - 3x²
then put it in the correct order
8x³ - 3x² - 4x + 3
