My approach to this question is:
w=[3 8 1];
y=[0 1 1];
x=[2];
a=polyval(w,x)
b=polyval(y,x)
a/b
Is it the right method to this question?

syms x
w = 3*x^2+8*x+1 ;
y = x+1 ;
a=subs(w,2) ;
b=subs(y,2) ;
val1 = a/b ;
%%
w=[3 8 1];
y=[0 1 1];
x=2;
a=polyval(w,x) ;
b=polyval(y,x) ;
val2 = a/b ;
[val1 val2]
Yes you are right.
