That is a quadratic equation.  Do you know how to solve it?

I'm not sure I am so bad at Trig would you use the quadratic formula?

wolf1728 · Answer

oops I'm sorry that is a quadratic equation in TWO unknowns
geez - that makes it a lot tougher.

tiffclifford13 · Answer

do you at least have a guess of what it would be im so lost

wolf1728 · Answer

x^2 + 4y^2 = 16 
It could be rewritten
-4y^2 = x^2 -16
-4y^2 = (X+1)*(X-1)
that's still not a solution

Subtract 16 from both sides and then factor. Please take a look at my various tutorials on the subject. They are very easy to follow and short. They also explain each detail and lastly they show how to use a graphing calculator to help you as well. I hope these help. https://www.youtube.com/playlist?list=PLsX0tNIJwRTxqIIcfpsTII9_xhqVIbQlp
