Initially you have an error in your expression A2 x^2, considering this as A2*x^2, let’s get to the problem.

Matlab has a very simple syntax: If you have a and want to multiply a times x, just use

a*x 

Case a be something more complex than just a simple variable or number, it is convenient to use parentheses to do the multiplication in the right way getting like this:

(a)*x
