Question

If x² + y² = 80 and xy = 12, find the value of (x-y)²

Answer 1

Answer:

56

I hope you understand the answer

Answer 2

Answer:56

Step-by-step explanation:

(x-y)square = x square+ y square - 2xy

(x-y)square = 80 - 2*12

(x-y)square = 80 - 24

(x-y)square = 56

so therefore,(x-y)square = 56
