Use the following information to answer question 18. In the prcxess of factoring the polynomial P(x) = x' + 313 + x 42, a student rewrites P(x) as the prcxfuct of two factors, where one factor is x 2. What is the remaining factor? 18. 19. 20. B. D. x3 + 5+ + Ilx 20 x3 +512 + lox +21 x 40 x3 + x2 2x+5 The polynomial represented by the graph to the right is If P(x) is a polynomial function where P O, and P(O) = 12, then _i_ isa factor of P(x), and _ii_ is a constant term in the equation of Nx). The statement above is completed by the information in row c.
