Hey there,
I am trying to process this "(x-2)*(x+1)^3" through matlab in way that I can have a result like this: ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/921804/image.gif)

However every time I try to perform this operation, matlab keeps on telling me that x is set to nothing, how can I solve this?
Thanks in advance!

Try using expand.
syms x;
expand((x-2)*(x+1)^3)

It's good to hear that you tried working out something by yourself. You need to create a symbolic variable for x.
syms x
