says error below-
Incorrect number or types of inputs or outputs for function extractCreationTimeDigits.

DISP has only one input argument.
syms f(x)
f(x) = (x^3) - (7*x) + 6;
x=solve(f(x)==0,x);
disp(x)

If you want to display the roots and the text in the same line, you will have to create a string before using disp, see this example for reference - https://in.mathworks.com/help/matlab/ref/disp.html#btnoykw-1
If you want to display them seperately, you can call disp() twice like this -
syms f(x)
f(x) = (x^3) - (7*x) + 6;
x=solve(f(x)==0,x)
disp('the roots will be')
disp(x)

Hi Bastian,
Try replacing
disp('the roots will be',(x))
with
fprintf('the roots will be %d. \n',x)
This should correct the string formating and print as desired.

Another option —
syms f(x)
f(x) = (x^3) - (7*x) + 6;
x=solve(f(x)==0,x);
disp(["the roots will be ",string(x.')])
.

syms f(x)
f(x) = (x^3) - (7*x) + 6;
x=solve(f(x)==0,x);
str = sprintf('%s ',x);
str(end) = [];
fprintf('the roots will be [%s]\n',str)

syms f(x)
f(x) = (x^3) - (7*x) + 6;
x=solve(f(x)==0,x);
fprintf('the roots will be [%s]\n',strjoin(string(x)))
