Hello, I am a new user of Matlab and I am trying to solve the following inequality
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1579526/image.png)
I tried to solve it with the code bellow and as you can see the result is wrong. I am seeking for intervals. What should I do?
syms x
ineq = x^2-2*x+7>12;
sol = solve(ineq, x)

syms x
ineq = x^2-2*x+7>12;
sol = solve(ineq, x,'returnconditions',true)
sol.x
sol.conditions
The result is two half-infinite intervals.
