Answer:
C.
Step-by-step explanation:
The answer is C, as as any value of m will make the equation true.
Such as if we used 2 as a substite value for m.

Lets simplify both equations:


Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.
Answer:
a^2+4b^2+2a+4b
