SOLUTION: when factoring can these two have the same answer? x^2-2xy+y^2 and x^2+2xy+y^2 if so is it because adding -xy and -xy is either -2xy or +2xy while +xy and +xy can only +2x

Question 4502: when factoring can these two have the same answer?
x^2-2xy+y^2 and x^2+2xy+y^2
if so is it because adding -xy and -xy is either -2xy or +2xy
while +xy and +xy can only +2xy

x^2-2xy+y^2= (x-y)^2
x^2+2xy+y^2= (x+y)^2
