Basically i need to convert it to the form \[x^2 / a^2 + y^2 / b^2 = c\]
yes, so divide both sides by 100 and post what you got.
I get it. So it's \[x^2 / 4 + y^2 / 25 = 1\] (: I just wasn't sure, because all three are square numbers so it looked like i had to do something with square roots...

yup, so what are a,b and c?
you figured it out, right?
yup! All good!! (: a=2, b=5, c=1
well the actual c value is root29. but my c in the equation is 1, and it has to be 1 anyway. O_o
actually, a= +2 and -2 b = +5 and -5
well yeah... i always ignore the +/- by accident. :P thank you!
