Answer:
2
Step-by-step explanation:
Expand the first and second pair of factors by multiplying each term in the first factor by each term in the second factor. Distribute the third factor by - 2m
(m² + m + 1)(m + 1) + (m² - m - 1)(m - 1) - 2m(m² + 1)
= m³ + m² + m + m² + m + 1 + m³ - m² - m - m² + m + 1 - 2m³ - 2m
Collect like terms
= (m³ + m³ - 2m³) + (m² + m² - m² - m²) + (m + m - m + m - 2m) + (1 + 1)
= 0 + 0 + 0 + 2
= 2
