15) Express the function in the form f(x) = (x - k)Q(x) + R(x) a) f(x) = 3x3 - 17x2 + 15x -25 K = 5 b) f(x) =9x3 - 16x - 18x2 + 32 K = 6 16). Given f(x) = x4-4x3 -7x2 +22x+24 Show that (x+2), (x -3) ) are factors of f(x). b ) Find the remaining factors of f. c) Use your result to write the complete factorization of f. d) List all the zeros of f
