Answer:
Step-by-step explanation:
The first step is to determine if some of the terms can be combined (added), so you have to look for like terms (like terms have the same variables with the same exponent).
We have the expression:
We can see that there are two elements that contain x ( and
) , this means that they are like terms and we can add them:
⇒
and this would be the final result, since there are no more like terms in this expression. The answer is D.

Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be
Another way of representing a quadratic is in "vertex form":
Now all you have to do is solve for a. You know that the vertex is and you have know the point of
. Now, all you have to do is plug in these values and solve for a.
Now you know the equation is , but you need it in quadratic form. All you have to do is solve is distribute the 6:
You get:
a = 6
b = 0
c = 2
