Answer 1

(3xy)*(-2x)*(-3y)= -6x^2y * (-3y) = 18x^2y^2

(1/2p)*(-2,5q)*(4pq)= -1,25pq * (4pq) = -5 p^2q^2

5-(13a+4b-7)+(3a-6,5b+1/3)+2a= 5 - 13a -4b+7 +3a - 6,5b +1/3 + 2a =

12 i 1/3 - 8a - 10,5b

12(5a-2)-(6a-7b)*8+3(3a-12b)= 60a -24 -48a + 56b + 9a - 36b = 21a + 20b - 24

12x^2 y-20x^3 y+16x^2 y^2= 4x^2y (3 - 5x + 4y)

8m^2 n^3 +10mn^2= 2mn^2 (4 mn + 5)

3a^2 +6ax^2= 3a (a + 2x^2)

-2x^2 -4x^3 y= -2x^2 (1 + 2xy)

15a^3 +5a^2= 5a^2 (3a + 1)

-7y^2 +14y^3= 7y^2 (-1 + 2y)

9xyz^3 +45x^2 yz^3= 9xyz^3 (1 + 5x)
