1 equation, 3 unknowns = 2 chances, slim and funk all.
if you can equate the RHS t zero u can get x ito y but thats prob no use to anyone, so the only valid answer is:
- inf < ? < inf.

y^2 + 2yx - 8x^2 can be factored in the usual way.
(y+4x)(y-2x)

y^2 + 2yx - 8x^2 = (y + 4x)(y - 2x)

are you trying to factor?
y^2 + 2xy - 8x^2
y^2 + 4xy - 2xy - 8x^2
factor by groups
(y^2 + 4xy)+ ( -2xy - 8x^2)
y(y+4x) + -2x(y+4x)
(y - 2x) (y+4x)
