M = x ^ 2 + 10x + 25 - x² + 10x - 25 + 3 + 20x = 40x + 3

N = a² + 6a + 9 - a² + 6a - 9 - 10a = 12a - 10a = 2a

b = x² + 6x + 9 - x² + 6x - 9 = 12x

c = x² + 6x + 9 + x² - 6x + 9 = 2x² + 18

d = a² + 2a + 1 + a² - 2a + 1 = 2a² + 2

e = a² + 2a + 1 - a² + 2a - 1 = 4a

f = 2x2 + 50

g = 9x² + 12x + 4 - 9x² + 12x - 4 = 24x

h = x⁶ + 6x³ + 9 + x⁶ - 6x³ + 9 = 2x⁶ + 18.
