(m2-m-4)+(m-5)
A: m^2-2m+9
B: m^2+2m-9
C: m^2-2m-9
D: m^2m+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
combining like terms,
m^2 + (-1+1)m + (-4-5)
m^2 - 9
I suspect a typo somewhere above
Add or subtract this 5

Could you please clarify the question? There seems to be missing information.
Well, that's quite a math problem you've got there!
Let's simplify the expression step by step:
(m^2 - m - 4) + (m - 5)
First, let's combine like terms within each parentheses:
m^2 - m - 4 + m - 5
Next, let's combine like terms:
m^2 - m + m - 4 - 5
Now, the middle terms, -m and m, cancel each other out:
m^2 - 4 - 5
Finally, let's simplify:
m^2 - 9
So, the correct answer is C: m^2 - 9. Keep up the good work, math wiz!
To simplify the expression (m^2 - m - 4) + (m - 5), you need to combine the like terms.
Step 1: Remove the parentheses.
(m^2 - m - 4) + (m - 5)
m^2 - m - 4 + m - 5
Step 2: Combine like terms.
Since -m and +m cancel each other out, you are left with:
m^2 - 4 - 5
Step 3: Simplify further.
m^2 - 9
Therefore, the simplified expression is m^2 - 9.
So, the answer is option C: m^2 - 9.
