3. Compute a polynomial via a product (Langtangen-2ed. 2.15) Given n+1 roots r0,r1,,rn of a polynomial p(x) of a degree n+1, the value of the polynomial can be computed by p(x)=i=0n(xri)=(xr0)(xr2)(xrn) Make a loop that computes the product to evaluate the polynomial at a given argument. Make the argument an input. Note: store the roots in a tuple
