I am using Maple to find the roots of a non-linear equation in one variable. When I solve the equation, I get only 2 negative roots whereas if I plot the graph of the function, it also shows that the graph cuts the positive x-axis at least once,
I have attached the graph and the code as an image.
What do I do to get that positive root?
P.S. I did the same thing on MATLAB too, but the program gave me the same negative roots.
