First factor the numerator. We need two numbers with a sum of 3 and a product of 2. The numbers 1 and 2 satisfy these conditions:
Now, look to see if there are any common factors that will cancel:
The 
in the numerator and denominator cancel, leaving

Transform the following equation from standard into vertex form:
Transform the following equation from standard into vertex form:
To take this standard form equation and transform it into vertex form, we need to complete the square. That can be done as follows:
We will complete the square on 
. In this case, our 
in our soon-to-be 
is 
. We therefore want our 
, so 
.
Since we are adding 
on the right side (as we are completing the square inside the parentheses), we need to add 
on the left side as well. Our equation therefore becomes:
Our final answer is therefore

Evaluate the following expression:
When we multiply expressions with exponents, we need to keep in mind some rules:
Multiplied variables add exponents.
Divided variables subtract exponents.
Variables raised to a power multiply exponents.
Therefore, when we mulitiply the two fractions, we obtain:

In the beginning, we can treat this as two separate problems, and factor the numerator and the denominator independently:
After we've factored them, we can put the factored equations back into the original problem:
From here, we can cancel the

Simplify to simplest terms.
Simplify to simplest terms.
The correct answer is 
. The numerator and denominator can both be factored to simpler terms:
The 
terms will cancel out. Leaving 
. While this is an answer choice, it can be simplified further. Factoring out a 
from the denominator will allow the 
terms to cancel out leaving
