Question 164398: a[2a-4(2+a)]
Answer by midwood_trail(310)   (Show Source):
You can put this solution on YOUR website! You gave us a[2a-4(2+a)] and said it is a fraction.
If so, where is the fraction?
I think this is a case involving the distributive rule.
In the brackets we have:
2a - 4(2 + a)....We simplify this first using the distributive rule to do away with the parentheses.
-4 times 2 = -8
-4 times a = -4a
We now have this in the brackets:
[-8 - 4a]
We now use the distributive rule again using the letter a outside the brackets.
a[-8 - 4a]
a times -8 = -8a
a times -4a = -4a^2
This is our answer: -4a^2 - 8a
==============================
If this is not what you want, then tell me where the fraction lies in your original question.
