Invalid syntax error with a simple code

15 views (last 30 days)
I am trying to write a simple MatLab code but continue to get an error that I can't find a fix for.
x = [-2 -1.5 -1 -0.5 0 0.5 1 1.5 2];
y = (x+x(sqrt(x+3)))*(1+2(x^(2)));
The error is at line 2, on the parenthesis that is bolded between the 2 and x. Any reason why?
Error: File: Assignment2.m Line: 2 Column: 26
Invalid expression. When calling a function or
indexing a variable, use parentheses. Otherwise,
check for mismatched delimiters.

tray this
x = [-2 -1.5 -1 -0.5 0 0.5 1 1.5 2];
y = (x+x.*(sqrt(x+3))).*(1+2*(x.^(2)));
