(a-b)(x-y)-(b-a)(x+y)
=(a-b)(x-y)+(a-b)(x+y)
=(a-b)(x-y+x+y)
=(a-b)×2x
=2x(a-b)
=(a-b)(x-y)+(a-b)(x+y)
=(a-b)(x-y+x+y)
=(a-b)×2x
=2x(a-b)

(a-b)(x-y)-(b-a)(x+y)
=(a-b)(x-y)+(a-b)(x+y)
=(a-b)[(x-y)+(x+y)]
=(a-b)[x-y+x+y]
=2x(a-b)

(a-b)(x-y)-(b-a)(x+y)
=(a-b)(x-y)+(a-b)(x+y)
=(a-b)(x-y+x+y)
=(a-b)*(2x)
=2ax-2bx
(a-b)(x-y)-(b-a)(x+y)=(a-b)(x-y)+(a-b)(x+y)=(a-b)(x-y+x+y)=(a-b)*(2x)=2ax-2bx
:(a-b)(x-y)-(b-a)(x+y) =(a-b)(x-y)+(a-b)(x+y)=(a-b)(x-y+x+y)=2x(a-b)
