If x^2 + y^2 = 16 and xy = 3, then (x − y)^2 =
Choose the correct choice from the following options:	A) 8	B) 11	C) 10	D) 17	E) 20
but you cannot take xy+ 3 to mean xy=-3..   only if xy+3=0, it will mean xy=-3..   rest your solution is perfect and you will get your correct answer as 16-2*3=10..   Answer 10
