Question 676016
{{{ 2(4-x)^2 = 4 - y^2 }}}



First, we need to get "x" and "y" on the same side. In order to do that, add "{{{ y^2 }}}" to each side.


{{{ 2(4-x)^2 + y^2 = 4 }}}



Divide both sides by four; after this, we can see that it is an ellipse due to its form {{{ x^2/b^2 + y^2/a^2 = 1 }}}


{{{ 2(4-x)^2/4 + y^2/4 = 4/4 }}}

{{{ (4-x)^2/2 + y^2/4 = 1 }}}
