Introduction to polynomials

What polynomial will be the result of multiplication of $-2x^3+4x^2-1$ and $x^2-4x-2$? In the answer field write down only coefficients divided by space. For example, if you got the polynomial $2-3x+4x^2$, then just write “2 -3 4”. Don’t confuse the order in which you write the coefficients!
