If x^2 + y^2 = 15 and xy = 3, then (x − y)^2 =	Choose the correct choice from the following choices
A) 8 B) 9 C) 14 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 15-2*3=9..   Answer 9
