Answer:
Step-by-step explanation:
So we start with:
To make this look more managable, lets seperate this into two binomials. Lets start with:
So how can we factor this? Lets look at what both the values have in common.
We immediatly see that they both have a coefficent of 2.
They also both have a h.
This means we can factor out a 2h from both and get:
Now lets move onto the other binomial we had:
Again, we can immediatly see that both values in this binomial have a 3.
Be careful however, make sure to factor out a -3, not a 3.
Another thing the two values have in common is a k.
This means we can factor out -3k to get:
Now lets reintroduce our first factored binomial back into this equation:
Notice that both factored binomials have (m-n)
Because of this we can neaten up our equation into:
How does this work?
Recall that the -3k will distrubute, or in otherwords multiply the (m-n) as . It works the same way in this form as well, since when you use foil, you multiply 2h by both m and -n, and -3k by m and -n.
And we see, if we multiply the binomials out again, we get:
So our answer is:
Hope this helps! :3

Based on this question, one thing that we would seriously consider would be the fact of first, doing 
first. By doing this, it would then give us our answer as 16. By us understanding this point of view, we would then consider that this would then be your answer. That would then include that there would then be 16 pairs of the "enantiomeric pairs", and that would then be the possible estimate.
