3. Find the following products:
(a) (2x - y)(3x - 5y)
(c) (p +9) (-9)
(b) (3a +2) (2a - 5)

​

Answer 1

Answer:

a) 2x(3x-5y)-y(3x-5y)

6x^2-10xy-3xy+5y^2

6x^2-13xy+5y^2

b) -9p-81

c) 3a(2a-5)+2(2a-5)

6a^2-15a+4a-10

6a^2-11a-10

Answer 2

Step-by-step explanation:

ans of a part is 6x²-13xy+5y²

ans of part c is -9p-9

ans of b part is 6a²-11a-10
