Question

if (x+y) = 9 and x²-y² = 27 then (x-y)² =​

Answer 1

(x - y)² = 9

explanation:-

(x + y) = 9

x² - y² = 27

(x + y) (x - y) = 27

9 × (x - y) = 27

(x - y) = 3

(x - y)² = 3²

(x - y)² = 9

Answer 2

Answer:

(x+y)2=10

Step-by-step explanation:

(x+y)2=x2+y2+2xy

⟹(x+y)2=6+2xy

⟹(x+y)2=6+4

(x+y)2=10
