Given a quadratic equation ax^2 + bx + c = 0, write a function to return its roots.
Second test case is faulty
This problem has been edited and is now solvable.
Perhaps the name of the function needs to be changed?
Agreed. The Test Suite is failing because it is (now) calling the built-in MATLAB function roots(p). https://mathworks.com/help/matlab/ref/roots.html
I don't think this problem will pass anytime as the test suite is faulty. In assertion your_function(x) is used and when i test my code Undefined function or variable 'x' occurs.
