Answer:
Step-by-step explanation:
v(x) - W(x) = x² + 2x - 4 - [x³ + 2x² + x + 5]
= x² + 2x - 4 - x³ - 2x² -x - 5
= x² - 2x² - x³ + 2x - x -4 - 5
= -x² - x³ + x - 9
Answer:
x³ - 3x² + x - 9
Step-by-step explanation:
V(x) - W(x) =
- x² + 2x - 4 - (- x³ + 2x² + x + 5) ← distribute parenthesis by - 1
= - x² + 2x - 4 + x³ - 2x² - x - 5 ← collect like terms
= x³ - 3x² + x - 9
