combining like terms,
m^2 + (-1+1)m + (-4-5)
m^2 - 9
I suspect a typo somewhere above
m^2 + (-1+1)m + (-4-5)
m^2 - 9

You wrote the question wrong...
but start by simplifying
M^2 - m - 4 + m - 5 = m^2 + -m + -4 + m + -5
Now combine like terms:
m^2 + -m + -4 + m + -5
m^2 + -m + m + -4 + -5
Equals: m^2 -9
but start by simplifying
M^2 - m - 4 + m - 5 = m^2 + -m + -4 + m + -5
Now combine like terms:
m^2 + -m + -4 + m + -5
m^2 + -m + m + -4 + -5
Equals: m^2 -9
