Answer 2

Answer:

Step-by-step explanation:

i) a(a-1)-b(b-1)

  Let's multiply a with (a-1) and b with (b-1)

we will get......

a²-a-b²+b

a²-b²-a+b

Using the identity

a²-b²=(a+b) (a-b)

(a+b)(a-b)-(a-b)

a-b is common so we can take that out

(a-b) [(a+b)-1]

(a-b)(a+b-1)

Thus factors are (a-b) and (a+b-1)

ii)(9x-1/5)²-(x+1/3)²

Using the identity

a²-b²=(a+b) (a-b)

we will get.............

(9x-1/5+x+1/3) ( 9x-1/5-x-1/3)

(10x+2/15)(8x-2/15)

Thus factors are (10x+2/15) (8x-2/15)
