Solve (x y)(x-1)-(x-y)(x 1)-2(xy 1)

Evaluate

x y (x - 1) - (x - y) (x \times 1) - 2 (x y \times 1)

Remove the parentheses

x y (x - 1) - (x - y) x \times 1 - 2 x y \times 1

Multiply the terms

More Steps

x y (x - 1) + x (- x + y) - 2 x y \times 1

Any expression multiplied by 1 remains the same

x y (x - 1) + x (- x + y) - 2 x y
