Question

which of the following is a factor of (x+y)^2- (x^2+y^2)

I am fine dear but in class can we talk later?​

Answer 1

Answer:

(x+y)3−(x3+y3)

= x3+y3+3xy(x+y)−x3−y3

= 3xy(x+y)

Hence, 3xy and (x+y) are the factors of the equation

hope it will help you brother

Answer 2

Answer:

$2y^{2}$

Step-by-step explanation:

$(x+y)^2- (x^2+y^2)$

$= x^{2} +y^{2}- x^{2} + y^{2}$

${+x^{2} and -x^{2} gets$ $cancelled$

∴ $y^{2} + y^{2} = 2y^{2}$
