Which is the greater quantity?
(a)
(b)
We show that there is at least one value of that makes the (a) greater and at least one that makes (b) greater:
Case 1:
(a)
(b)
(b) is greater here
Case 2:
(a)
(b)
(a) is greater here

Compare your answer with the correct one above
Which of the following is equivalent to ?
We can best solve this by factoring 4 from both terms, and distributing it out:
Compare your answer with the correct one above
Simplify the below:
In order to simiplify we must first distribute the -2 only to what is inside the ( ):
Now, we must combine like terms:
This gives us the final answer:

Simplify the below:
We must use the distributive property in this case to multiply the 4 by both the 3x and 5.
