Hi Christopher,
The following lines of code will do the trick:
>> syms alpha delta
>> solver = @(x,y) solve(x ==alpha / delta^2 , y ==(( (3*alpha*(1+delta)^2) + ( (1+alpha)*(1+alpha*delta^2)))^(0.5))/((1+alpha)^2), alpha, delta,'IgnoreProperties', true);
>> sol = solver(x,y);
Pass the desired values of x and y to the function named "solver". This will return a structure that contains the values of "alpha" and "delta", for the given x and y values.

Your delta is always squared so algebraically both negative and positive values are valid. The message is warning you that multiple solutions have been returned but that they might not all make sense in the overall context.
