1. I am not sure how to do this problem:

Use the quadratic formula to solve the following equation for x.

I don't know how to start this one.

What do I recognize?
This equation is an elipse.
It cannot be further factored.
Possibly something could be done with trig since the equation is an elipse, but I don't know what.

2.

3. I should probably leave this one for the mathematicians but I'm going to guess that to use the quadratic formula you would have to put it in the form of a quadratic equation. That would mean pretending y is a constant, then solve for x in terms of y.

4. That's a good idea, but when I say
a = 4
b = -2y
c = 3y<sup>2</sup> - 2

x = (y +/- i ( 11y<sup>2</sup> + 8 )<sup>1/2</sup> ) / 4

Precisely
