{{{2y^2+4xy=x^2}}}


{{{2(y^2+2xy)=x^2}}}


{{{y^2+2xy=(x^2)/2}}}


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


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


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


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


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


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


{{{(y+x)^2=(3x^2)/2}}}


{{{y+x=""+-sqrt((3x^2)/2)}}}


{{{y+x=""+-x*sqrt(6)/2}}}


{{{y=-x+-x*sqrt(6)/2}}}


{{{y=(-2x)/2+-x*sqrt(6)/2}}}


{{{y=(-2x+-x*sqrt(6))/2}}}


{{{y=(-2x+x*sqrt(6))/2}}} or {{{y=(-2x-x*sqrt(6))/2}}}
