%28x-h%29%5E2%2Fa%5E2-%28y-k%29%5E2%2Fb%5E2=1
given:
Center at (-2,2)=>h=-2, k=2
a focus at (6,2)=> focus is (h+-+c, k+) = (6,2)=>{-2 - c=6}}}=>-2-6=c=>c=-8
a vertex at (4,2).=> (h+%2B+a, k) = (4, 2)=>-2+%2B+a=4=>a=-2-4=>a=-6
b%5E2=c%5E2-a%5E2
b%5E2=%28-8%29%5E2-%28-6%29%5E2
b%5E2=64-36
b%5E2=28
equation is:
%28x-%28-2%29%29%5E2%2F%28-6%29%5E2-%28y-2%29%5E2%2F28=1
%28x%2B2%29%5E2%2F36-%28y-2%29%5E2%2F28=1
