A polynomial f(x) has the factor-square property (or fsp) if f(x) is a factor of f(x2). for instance, g(x) = x 1 and h(x) = x have fsp, but k(x) = x + 2 does not. (a) are x and x 1 the only monic fsp polynomials of degree 1? (b) note that x2, x2 1, x2 x, and x2 + x + 1 have fsp. list all the monic fsp polynomials of degree 2. (c) observe that x2 and x2 x arise from degree 1 cases, but x2 1 and x2 + x + 1 are new, not expressible as a product of two smaller fsp polynomials. list all the new monic fsp polynomials of degree 3. can you nd all the new monic fsp polynomials of degree 4 ? (d) many examples found above have integer coecients. do answers change if we allow coecients to be any real numbers? or if we allow polynomials whose coecients are complex numbers?

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
