Question

simplifique (x-y)^2 -2 (x-y)÷ax-ay+2x-2y
$(x - y) ^{2} - 2(x - y) \div ax - ay + 2x - 2y =$
me ajudem pfv

Answer 1

$(x - y {)}^{2} - 2 \times (x - y) \div ax - ay + 2x - 2y \\ {x}^{2} - 2xy - {y}^{2} - \frac{2(x - y)}{a} \times x + ay + 2x - 2y \\ {x}^{2} - 2xy - {y}^{2} - \frac{2 {x}^{2} - 2xy }{a} - ay + 2x - 2y \\ \frac{a {x}^{2} - 2axy + a {y}^{2} - (2 {x}^{2} - 2xy) - {a}^{2}y + 2ax - 2ay }{a} \\ \frac{a {x}^{2} - 2axy + a {y}^{2} - 2 {x}^{2} - 2xy - {a}^{2} y + 2ax - 2ay }{a}$
Espero ter ajudado!
