a (x-y) - b (x+y)

(x-y) 10 = 10*x-10*y

(a+b-c) 2 = - 2*c+2*b+2*a

(a-b) 5a = 5*a^2-5*a*b

a (x-y) = a*x-a*y

(a-b) (-6) = 6*b-6*a

2 (a+b) + 4 (a+b) = 6*b+6*a

4-2 (x+1) = 2-2*x

2 (a-b) - 3 (a+b) = - 5*b-a

4 (x-y) + 7 (x-y) = 11*x-11*y

2a-3 (b-a) = 5*a-3*b

a (x-y) - b (x+y) = (-b-a) * y + (a-b) * x

(х-у) 10=10 х-10 у

(a+b-c) 2 = 2 а+2b-2c

(a-b) 5a=5a*a-5ab

a (x-y) = ax-ay

(a-b) (-6) = - 6a+6b

2 (a+b) + 4 (a+b) = 2a+2b+4a+4b=6a+6b

4-2 (x+1) = 4-2x-2=2-2x

2 (a-b) - 3 (a+b) = 2a-2b-3a-3b=-a-5b

4 (x-y) + 7 (x-y) = 4x-4y+7x-7y=11x-11y

2a-3 (b-a) = 2a-3b+ab

a (x-y) - b (x+y) = ax-ay-bx-by
