I have two expressions:
expr1 = e^2/(8 + 4*e + e^2)
expr2 = (d^2 - 2*d*e + e^2)/(8 + d^2 - 2*d*2 - 2*d*e + 4*e + e^2)
and one inequality:
0 < d < e < 1
I need to decide which expression is greater, and if one is not always greater, under what circumstances they change order. Equally, is it a decidable question?
