Hello sage-support team, im in the learning process of sage, so im working on some basics problems, like solving inequalities. And when i try to solve this problem (4*x + 5)/(x^2)>=4/(x+5) im getting this answer [[x < -5], [x >= -1]], which is wrong. (http://www.wolframalpha.com/input/?i=%284x+%2B+5%29%2F%28x^2%29+%3E%3D+4%2F%28x%2B5%29) cuse its including zero in the solution and that's not possible because there's a pole there. This is what im doing:
sage: f(x) = (4*x + 5)/(x^2) sage: g(x) = 4/(x+5) sage: solve(f(x)>=g(x),x) And i get the answer i post, i am doing something wrong? Thanks in advance for this space and for your time to at least watching this post of the many you guys attend. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
