Hi!
I don't understand how a.(x-y) -b(x-y) = (x-y) (a-b) ???
Please help...

Answer 1

Answer:

a.(x-y) - b (x-y) = (x-y) (a-b)

Step-by-step explanation:

Taking a.(x-y) - b (x-y)

Here, (x-y) is common between a and b

So we take (x-y) out as it is common

As (a-b) is left out it becomes (x-y) (a-b)

Hence a.(x-y) -b(x-y) = (x-y) (a-b)

Hope you understand
