Question

(x - 3)^2 - 9y^2 = 9 Can someone explain how to convert this into y=?? form, please?

Answer 1

put everything on right side except y terms
\[-9y ^{2}=9-(x-3)^{2}\]

then try to make left side y
\[y=\sqrt{((x-3)^{2}-9)/9}\]

Answer 2

There is a difference of squares under the square root if u like to tidy it up a bit.
