Accepted Answer. MATLAB assumes that symbols might have complex values unless you tell it they are not complex. For complex values, sqrt (x^2) is not the same as x. For that matter, sqrt (x^2) is not the same as x even just for negative real values. If you know for sure that your values are nonnegative, then add an assumption about that, such as.First, I tried to solve for each unknown separately. i.e. solve first equation for x_1 in terms of x_2,...x_4.
