Can the Product of Two Polynomials Result in a Single Term?

By assuming that we are talking about polynomials with real coefficients. Suppose that the polynomials are,

$\mathrm{<i>P(x)\; =\; ax^p + \; ...\; + \; bx^q</i>}$
$\mathrm{<i>Q(x)\; =\; cx^r + \; ...\; + \; dx^s</i>}$

Russian Peasant Multiplication

This method involves a process of halving and doubling, which reduces one factor to powers of two and uses the distributive property of multiplication over addition to calculate a product.

                              25                    37

                              12                    74

                              6                      148

                              3                      296

                              1                      592

                            -------------------------           Therefore, 37 + 296 + 592 = 925

                                                      925                              ( 25 x 37 = 925 )
