Answer:
Step-by-step explanation:
I'll group it in a way that I can get common factor numbers.
I can see that 2 and 4 are factorable by 2 and 3 and 6 by 3
What do these have in common? 2 and 4 have a 2 in common and they also share an x.
Now, what does 3 and 6 have in common? a three. However, we don't usually let our x's be negative, so in order to keep it positive, extract a -3 instead of 3
so, -3/-3 = 1
6/-3=-2
Leaving...
Now, put all together.
Look, what do they have in common? Exactly, both have
, simply add the terms outside the parentheses and use the same parentheses.
If you don't understand why I did this, let x-2 = y
So, you have...
Factor that y.
Replace y with our original value.
Same result.
