Question: Solving inequality with one variable and one parameter

Hello to everyone,

I want to solve the following inequality:

solve(b^4-(2-d)*b^2-2*d*b+1+d > 0, [b]), where b is my variable and d is a pamater in (0,1]. 

When I try to sovle this I get a message "Warning, solutions may have been lost" and from the official maple website they suggest to reformulate the problem.

Is there anything I can do to solve the above inequality?

 

Thanks in advance!
