Dear Master

I am a young researcher in numerical linear algebra. For some calculations,
I used your "Maxima" software. But I have some problems with some commands
such as:

 integrate(1/(r+s*x+t*x^2)*1/sqrt(1-x^2), x, -1, 1);

give me this message:
"Is  "4*r*t-s^2"  positive, negative, or zero?"

I tried different answers but did not?! What do you suggest?

Thanks for your attention and kindness.
Best wishes.
