To write − x+y x−y - x + y x - y as a fraction with a common denominator, multiply by x+y x+y x + y x + y. x −y x +y ⋅ x−y x−y − x+ y x− y ⋅ x+y x+y x - y x + y ⋅ x - y x - y - x + y x - y ⋅ x + y x + y. Write each expression with a common denominator of (x+y)(x− y) (x + y) (x - y), by multiplying each by an appropriate factor of 1 1.
