a = 3 x 4x - 3 x 2 + 5 x 1 + 5 x 3x = 12x - 6 + 5 + 15x = 27x -1

b= -5 x 2 + 5 x 7x -4 x 2x - 4 x -3 = -10 + 35x - 8x + 12 = 2 + 27x

c = -4 x 3x -4 x 1 + 3 x -2 + 3 x -8x = -12x - 4 - 6 - 24x = - 36x - 10

D = 4 x 2x - 4 x 6 + 2 x -3 + 2 x 2x = 8x - 24 - 6 + 4x = 12x - 30

e = -5 x 3 -5 x -2x - 3 x -3x - 3 x -4 = -15 + 10x + 9x + 12 = -3 + 19x

f = 2x - 6x² - 8x + 4 - 15x² + 20x = -21x² + 14x + 4
