Do you know where to start?

2. anonymous

No I'm guessing the (x)

3. mchilds15

Well, yeah. Just change the f(x) to y. It kind of makes it easier when you look at it. Now, how do you plan to solve it?

4. mchilds15

(you can't factor it)

5. anonymous

Solving for (y)

6. mchilds15

Yes, but to do so, you're going to have to apply the Quadratic Formula Does that sound familiar or am I getting way ahead of you?

7. anonymous

Eh? Yea u kinda lost me I don't really understand it that way.

8. mchilds15

Okay... Here, go to http://www.tiger-algebra.com/ ^this site will not only give you the answer but show you the steps to get there. It helped me get through high school ;)

9. mchilds15

$\frac{ 3\pm i \sqrt{23} }{ 4 }$ This was my answer btw...

10. mchilds15

Then again I used the quadratic formula. You could find a different answer by completing the square. I don;t know where you are in your lessons... Does Completing the Square sound familiar?
