There is not a formula for everything need more data
the answer is A but im just guessing ya know?
The answer is one of the last two. I am pretty sure that it is corresponding but I could be wrong.
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:
1/2d + 6 = 1/2 (d + 3)
Hope this helps!
