(m - 1) (m^2 + 2m +6)
I keep getting m^3 + m^2 + 5m - 6...im wrong though.probably

(m - 1)(m² + 2m + 6) =
m³ + 2m² + 6m - m² - 2m - 6 =
m³ + 2m² - m² + 6m - 2m - 6 =. . collecting like terms
m³ + m² + 4m - 6

Multiply m times (m^2). Also times 2m. Also times 6. This gives you (m^3 +2m^2 +6m).
Then multiply -1 times (m^2). Also 2m. Also 6. This gives you (-1m^2 -2m. -6). Add the two results together. It gives you (m^3 +m^2 +4m -6).

m^3 +2m^2 +6m -m^2 -2m-6= m^3+m^2+4m-6

(m - 1) (m^2 + 2m +6) =
m³ + 2m² + 6m
00 - m² - 2m -6
--------------------
m³ + m² + 4m - 6
Simplify:
m²(m + 1) + 2(2m - 3)

You're almost there!
The coefficient of m is 6-2 or 4, not 5.
The rest is fine.
