(x + y)²=bantu jawab pake cara pliss

Penjelasan dengan langkah-langkah:

$(x + y {)}^{2} \ = (x + y) times (x + y) \ = x times x + xy + xy + y times y \ = {x}^{2} + xy + xy + {y}^{2} \ = {x}^{2} + 2xy + {y}^{2}$

Jawaban:

(x+y)^2 = 0

x^2 + y^2 + 2xy = 0..………..Eq(1)

(x – y)^2 = 0

x^2 + y^2 – 2xy = 0……………Eq(2)

Eq(1) + Eq(2),

2x^2 + 2y^2 = 0

2(x^2 + y^2) = 0

x^2 + y^2= 0

Answer:

x^2 + y^2 = 0
