How to do the following questions in high school mathematics?

Let the elliptic equation and hyperbolic equation be x2/a12+y 2/b12 =1,x2/a2 2-y 2/b2 2 =1respectively.

According to the known c12 = C2 2 = C2C2, that is, a12-b12 = a22+b22 = C2,

So B 1 2 = A 1 2-C 2, B2 2 = C2-A2 2,

Their focal triangle areas are equal, that is, b12 * tan (π/6) = B2 2 * cot (π/6).

So (a12-C2) *1/3 = C2-a22,

So a12-c 2 = 3 (c 2-a22c2-a22),

The two sides divided by c 2 are (a1/c) 2-1= 3 (1-(a2/c) 2).

So (A 1/c) 2+3 (A2/c) 2 = 4,

That is 1/E 1 2+3/E2 2 = 4.
