Answer 1

Odpowiedź:

a) 10p^2+4pq+15pq+6q^2=10p^2+6q^2+19pq

b) 3a^2-12ab+2ab-8b^2=3a^2-8b^2-10ab

c) 6x^2-4xy-9xy+6y^2=6x^2+6y^2-13xy

d) 5m^2-2mn+10mn-4n^2=5m^2-4n^2+8mn

e) 10a^2b+15a^3-2b^2-3ab

Answer 2

A) = 10p² + 4pq + 15pq + 6q² = 10p² + 19pq + 6q²
b) = 3a² - 12ab + 2ab - 8b² = 3a² - 10ab - 8b²
c) = 6x² - 4xy - 9xy + 6y² = 6x² -13xy + 6y²
d) = 5m² - 2mn + 10mn - 4n² = 5m² + 8mn - 4n²
e) = (5a² - b)(2b +3a) = 10a²b + 15a³ - 2b² - 3ab
