Write a program for a user-defined function to multiply a polynomial. Name this function: P=polymult (p1, p2 ) The first and second input variable p1,p2 is a vector of the coefficients of the first and second polynomials, respectively, and the output variable is a polynomial resulting from the multiplication process. Use the function to multiply polynomials: 2 f(x) = x -7X+11 x-4X-5x-2 | %3D +, (x) = 9 x-10 x +6 2. *without using the conv. function
