zadanie 1
a = xy + 4x + 3y + 12
b = mn - 2m + 6n - 12
c = ab - 3a - 7b + 21
d = 6 + 4y + 3x + 2xy
e = 15m - 5mn + 3 - n
f = 15q - 10 - 6pq + 4p
g = 6ab - 8a - 9b + 12
zadanie 2
a = p² - 2p + 4p - 8 = p² + 2p - 8
b = -3a + 12 + a² - 4a = a² - 7a + 12
c = 2x² + 6x + 5x + 15 = 2x² + 11x + 15
d = 8m² - 20m + 2m - 5 = 8m² - 18m - 5
e = 20 + 15p - 4p - 3p² = -3p² + 11p + 20
