Factories: (x – 2y)2 + 4x – 8y

1.	Factories: (x – 2y)2 + 4x – 8y
Answer» (x – 2y)² + 4x – 8y = (x – 2y)² + 4(x – 2y) = (x - 2y)(x - 2y) + 4(x - 2y) = (x - 2y){(x - 2y) +4} = (x – 2y)(x – 2y + 4) So we get, (x – 2y)² + 4x – 8y = = (x – 2y)(x – 2y + 4)

Answer»

(x – 2y)² + 4x – 8y

= (x – 2y)² + 4(x – 2y)

= (x - 2y)(x - 2y) + 4(x - 2y)

= (x - 2y){(x - 2y) +4}

= (x – 2y)(x – 2y + 4)

So we get,

(x – 2y)² + 4x – 8y = = (x – 2y)(x – 2y + 4)
