Locus of points such that the sum of whose distances from A(0,-2) and B(0,2) is 8(adsbygoogle = window.adsbygoogle || []).push({});

I plotted the points its a straight line on the y axis. I sub both points into the distance formula (seperate distance formulas) and then made the eqn = 8 I squared both sides getting rid of the square root and then simplified and got

[tex] 2x^2 +2y^2+8=64 [/tex] I think I did this question wrong plz help me
